Path following

Guards can now be called on to find, then follow paths. Also the I took away the streamlining of the path, it was overkill to do that while drawing the path and it works better to do it while the guard walks, that way I can use his position to check if he can see any upcoming nodes as he walks and if he does, jump to those instead of any before them. The colored dev lines don't look as organized though :(
Also guard movement is smoothed so it looks pretty natural when he turns corners and along with the realtime checking for a more streamlined path it means that the movement looks a lot less node based because he doesn't need to get to the node before he turns, he just turns when he has a straight path to the next node. In the above picture you can see a non-steamlined path, the script then "sees" points one two and three drawing yellow lines to them, then because it can't see four yet it walks to three.

Working A* pathfinding

The A* pathfinding system is now functional and very efficient, guards quickly generate a route to the player using the nodes placed on the map and then optimize the route deleting any superfluous nodes on the path. I ended up not using the arrays built into the nodes of closest other nodes because I would have to use that array and the open list of nodes on the pathfinding script at the same time constantly cross checking that a node in the node's array was also on the script's array and then finding the chosen node from the node's array in the script's array to remove it from the open list. I decided it would be more efficient to just check all nodes.
(Above) The pathfinder with no optimization finding the first route through the nodes to a set point. (Below) With optimization code (And fewer nodes) the script finds an efficient path to the target. Also switched to spherecasting instead of raycasting because rays were cutting corners too close and guards couldn't get past comfortable and from time to time would try to find paths through arrow slits.
One more addition needs to be made before the script is ready to be implemented by the guard movement script, that is back tracking. I haven't run into any problems that would need it yet, any failures of the pathfinding so far have been node placement related but as levels get larger and more complex it's probable that guards will start taking dead ends and the pathfinder will get stuck at the ends of hallways instead of reaching the target. To solve this the script needs to be able to backtrack one node at a time. So ad the end of the dead end it realizes its mistake and moves back one node and looks for a new closest node disregarding the previous choice, either it finds a new path or it moves back again until a new path is available.
Once all this is implemented guards will need some sort of smoothing to make their paths look more natural, also they may run this script over the course of a few frames to make sure it always runs smoothly and the guards don't need to move immediately anyway, a few frames to notice the sound or sight, then a few frames shouting out or looking around will only look natural.

AI pathfinding nodes


I started writing an A* pathfinding system with branching nodes, each node is linked to it's closest eight nodes for more efficient path plotting. I wrote a script that would cycle through them and link them to their eight closest nodes who's paths don't intersect walls or obstacles. Above is the turn out when I got it right, below is the result when I accidentally required rather than disallowed raycasts intersect with walls and obstacles.



Two more examples, above just two links each, below is four which is probably the one I'll stick with for speed.

Light level


Light level is the first thing I've completed, the concept for measuring light seemed simple but it was so essential to the gameplay I decided to do it first to make sure it could be done efficiently and accurately.

The method is quite simple, since we're already using light objects in unity to create light we can add extra code to each of them to check how much they're lighting up the player. All the check does is raycast the distance from the light to the player to check for walls in the way, then if it finds the path clear it measures the distance to the player and assigns a percentage based on the distance. Unity handled all of this very well and the code ran smoothly with no difference in frame rate.

Past this there are still a lot of improvements to be made to this system, things like ambient light, how close the player is to walls and special areas like outside or rooms with windows. Also the checks run to the centre of the player so sides of the player poking out doorways won't register as putting the player in light and if it's dark in the middle of a room the player can walk through undetected even though logically the character would make a silhouette on the wall behind him if it was lit well enough. That said there's always room for improvement but as long as the basic system works I can go ahead with the project.

Garshasp Temple of the Dragon Review

Hi, my name is Nik and today i am reviewing:


Garshasp Temple of the Dragon is a simple spectacle fighter.


The story starts with Garshasp and his wimpy brother going in the Temple of the Dragon, in search of the Mace of Trit. Now that is the first problem - this game has a story. Its a problem, because of two things - the worst voice acting i have heard in a long time, and unskippable cutscenes.

The game would have being better, if the story wasn't there at all.



At least the gameplay is better then the story, but not by a lot. The biggest problem is that there is no camera control, therefore you will find your self making blind jumps, or being hit by an enemy you didn't saw, and this gets really frustrating after a while.

Also Garshasp Temple of the Dragon is a really slow burner, because you dont have access to your cool attacks at the start, you have to unlock them by leveling. You cant get to the interesting part, without dying of boredom.



As far as combat goes its standard spectacle fighter like Devil May Cry, or God of War, but its just not as good. This mostly comes from the bad sound effects, that make you feel weak and puny, instead of  making you feel like a bad ass, killing machine.

To add insult to injury, Garshasp is plagued by frame dropping, even on the lowest settings and this makes me think that this game is more of a joke than anything else.



To top it all of, Garshasp Temple of the Dragon is a disappointing and boring experience. 



I hope you liked my review of  Garshasp Temple of the Dragon .

Things you find on the internet...

I check the blog statistics every now and then (not often enough if I wanted to manage this blog more professionally - but hey... I am an artist at the core not a blogger)... but... there was a referring site that looked strange. I followed the link: 

http://gamerboom.com/archives/60814

and found this:

Someone took the time and effort to translate all my gamasutra blog posts to chines - taking out my text from the images and putting new text in. 

I don't speak any chinese so I can't say if they did a good job or not - one thing is for sure - they do a quick job. The tutorials appear on their site a day later... and they have been doing it right from the start.

The do mention me as the author - so... thanks GAMERBOOM.com for the extra exposure. :)

Dogfight 1942 Review

Hi, my name is Nik and today i am reviewing:



Dogfight 1942 is an arcade flight sim set in world war II.

Do i really need to know about the story? You are a pilot in WW2, you must follow orders, engage is aerial dogfights, and complete missions. That is all you need to know to enjoy the game.

Before i start the review, i want to point out the this game is best played with a xbox 360 pad, and i strongly recommend using one. Also there is no built-in in joystick support.


The most important thing in a flight sum is the plane handling and i am happy to say that Dogfight 1942 doesn't disappoint. All of the planes have weight, inertia and they cant turn on a dime, this makes them believable and enjoyable to fly. For fans of WW2 planes, the game  also provides a large selection of over 20 planes.

The sense of speed is also fairly good, because of effects like zooming out, and motion blur. And this is where my first complaint come is, the game has too much motion blur, and no option to turn in down. 


Now lets talk a bit about the guns. Every plane has several machine guns, rockets ,and if the mission requires it - bombs. I would like to point out the the bombs hit detection is kind of bugged, and sometimes when you hit the target - it doesn't take any damage.
Still the weapons feel very destructive, because of the good sound and visual effects. Probably half of the budget went in to the explosions - they are just very detailed and beautiful.

Now i can tell you where the budget was extremely small - writing and voice action. Some of the lines are really really bad, because they tried to imitate the military lingo of the '40s and they failed completely. They also failed in the british accents, which are juts horrible. At least the american accents are a bit better - i can listen to they without wanting to kill myself.


But the biggest problem i have with the game, is that it runs terrible. Even on my middle class PC is lag and stutters, on minimum setting. And that is just unexceptable, when i know for a fact that this PC runs better looking games, without this bugs. I hope that this gets resolved soon, so i can give this game a positive recommendation. 


To top it all of, Dogfight 1942 is a fun, fast arcade flight sim, with some serious performance issues, and terrible voice acting.

I hope you liked my review of  Dogfight 1942.

Gotham City Impostors Review

Hi, my name is Nik and today i am reviewing:



Gotham City Impostors is a multiplayer FPS, that takes place in Gotham City.  

The setting is really unusual and unique. For some reason Batman and Joker are gone. Therefore some of Gotham's citizens dress as Batman, and continue his mission of protecting the city. But every "hero" needs a villain, so the criminal organizations cosplay as Joker, is an effort to bring chaos to Gotham. 

As you can probably see it is a funny, batshit crazy story, that doesn't take itself seriously.

This craziness is present in every aspect of the game, from the funny tutorial, to the impractical costumes. For example, you can have a fat Joker, wearing a kilt. You can have a skinny Batman, with a bat symbol taped to his chest.
This game will just make you smile.

But what really matters is the gameplay, and it doesn't disappoint one little bit. The weapons have great sound effects, which gives you the feeling of power, every time you shoot. I can even go as far, as to say that it feels better the Call of Duty in some places.


But the thing that really sets Gotham City Impostors apart from other modern military shooters, is the gadget systems. They are usually things that utilize thevertical elements of a map, like a Grapple Gun, or a Jetpack. That type of vertical play is usually a feature of arena shooter, like quake, so its nice to see it making a comeback. 



One of the problems that the game has, is that it doesn't know what it wants to be. Some of the weapons are strange and funny, like the slingshot that fires grenades, or the cannon that shoots homing parrots. And on the other side, you have normal machine guns, SMGs and Sniper Rifles, and that is boring, I would really like to see the developers embracing the batshit crazy nature of the game, and give us crazy weapons. 

Speaking of Sniper Rifles, that is the only imbalanced thing that i have seen so far, and i really hope that it gets fixed soon, because it really gets on my nerves.


Now, since this game is free-to-play, on PC, i have to address their model. I can very happily say that it is not pay-to-win. You can get every non-cosmetic item, if you just play for free. But if you decide to pay, you can get XP boosts, cosmetic stuff and items don't impede the balance in any way.

Still as other free-to-play games the matchmaking is a bit of a problem. If you want to play Team Deathmatch, good because that is the only mode that you can get enough people. If you want to try Capture The Flag, or Kill Confirmed, you just cant.




To top it all of, Gotham City Impostors is a game with a lot of customization, good sense of humor and fun combat. 

I hope you liked my review of  Gotham City Impostors.

Borderlands 2 Review

Hi, my name is Nik and today i am reviewing:



Borderlands 2 is a FPS, RPG with a metric tone of weapons.

The story is set after the opening of the Vault from the first game. Because of it, the world of Pandora now has Eridium, which is extremely valuable mineral. Also for some reason there is another Vault filled with treasures, just waiting to be discovered.And of course your are a Vault Hunter searching for the Vault.


When you start the game, you get a vision from the Guardian Angel. She tells you to follow some ClapTrap, just like in the first game. 
Then comes the first problem i have with the game - the first 2-3 hours are boring as hell. No interesting characters, weapons, or locations. The game really kicks off when you get to the city of Sanctuary. The game is a really slow burner, but once you get to the city the story, characters and cheesy jokes get much better.


Now gameplay, that is the second problem i have with Borderlands in general. The weapons feel weak, with very small recoil and bad sound effects. This makes the game really boring, especially if you are playing alone. So if you dont have friends to play it with, you will probably hate it. 
One good thing that i can say about weapons, is that they starts getting cool effects, much earlier then in the first game, but that is about it.

Another big gameplay problem, is the vehicle handling. Who was the genius who taught that you should steer with the mouse, for the PC revision? This kills all enjoyment, you may have had in a vehicle.


Still Borderlands 2 deserves to be praised for the PC port. Its is perfect in every way - from the massive array of video options, to the gampley options. You can adjust the gameplay to your preferences, and that certainly wasn't the case with the first game.

The RPG elements are close to those of Borderlands 1 - a talent tree with lost of passive effects, many randomly generated weapons that you change frequently, and a fairly interesting side quest.


To top it all of, Borderlands 2 is more of the same, therefore if you liked the first game, you will love this one, but i certainly did not.


I hope you liked my review of Borderlands 2 .

Tony Hawk's Pro Skater HD Review

Hi, my name is Nik and today i am reviewing:



Tony Hawk's Pro Skater HD is a HD remake of Tony Hawk's Pro Skater 1 and 2. What else could it be?

As the name would suggest, this is a game about skateboarding. You have to do tricks and complete missions in 2 minutes. The objectives range from getting the high score, to collecting letters of SKATE. Its a compelling and well executed concept.

This remake has the same fluid and satisfying gameplay of the original games, with added improvements like better animation quality and, of course, HD textures.


Since this game contains two game, they are not 100% complete. There are only 7 maps,but this is a good thing, since these are the best maps.
Due to legal issues is the soundtrack is not the same (list of songs) the only song from the original games is Superman. It is still a good soundtrack, but its just not the same.

But the biggest missing thing is the map editor. I loved making my own maps in the old games,  and i am king of sad that i cant do it in this game.


The thing the made me rage the most, however, is the atrocious PC port. I haven't seen a worst port in years, no graphical options AT all, no resolution change, no Vsync, and no Windowed mode. Also you cant rebind the keys. If you want to change anything, you have to edit the .ini filed manually, and that is just unacceptable. 

At least it works with a 360 pad, cuz god knows that its impossible to play Tony Hawk games with a keyboard. Take this is a warning, don't buy this game, if you don't have a 360 pad (or something similar)


To top it all of, Tony Hawk's Pro Skater HD is a very good HD remake with a terrible PC port.

PS:THPS3 DLC has being announced, and i am kind of exited, because 3 and 4 where my favorite games from the series.


I hope you liked my review of Tony Hawk's Pro Skater HD.
