Zombie Outrage 2 (ZO2 Updates)

[TheAustech]

Okay, so since the lighting seems to be one of the problems, and lighting is one of the main things I plan on using to it's fullest in the game. I'm working on a completely new lighting system.







I'm working on a way to get it more optimized though. Right now three lights drop the fps to about 50. And that's without Box2D running or any other entities

sweet... hey get on tinychat xD

Which channel is it? Long dev knights? XD

[eatcomics]

yes... minus the k... although....

Man, thats pretty damn sweet. If you added some alpha blending to the light it would look so good.

So, I said that I would update the lights. The latest post a made was some little picture of a light with a simple rectangle. Hours have past, yet no update. Well, here it is. People wanted it, and it's added.

The New Lighting System

Features:

• Ray Casted Lights
  Per Boxel Lighting (Will be Explained)
  Shadows
  Optimization (Yet Still in the works)

Optimization Techniques:

Per Boxel Lighting - Ever heard of per pixel things? Things like per pixel lighting, per pixel collision. Well, in case you didn't know, that can be quite a CPU hog. But it's because it very precise. When colliding, it's to the very pixel (hence, "per pixel"), when lighting, it's down to the very pixel. So what is per boxel? Per Boxel is just some clever name I made up. Here's how it works:

It shoots rays of lights (ray casting) in the angle of the lighting. This is very accurate. But when looking for Blocks (things that block the light and casts a shadow), it doesn't cast a shadow down to the exact pixel. Instead, it stops based off the Block's Bounding Box. This allows the lights to reflect correctly, yet still maintaining a reasonable frame rate. The only downfall is that it's not 100% correct, meaning there may be some things that will cast a noticeable box shadow, when the block is a completely different shape.

Light Spacing - The way that lights get the roundness and the width of it's light is stored in it's class called "AngleSpacing". Yet the Light System itself it what takes advantage of it. The light system holds a variable that can be changed to set the spacing. What this does, is it determines how much spacing between the light rays until it reaches it's full light. The higher the spacing, the less light rays, yet the better the performance. Examples of changing the value are:
Spacing at 5.
Spacing at 2. You can see more light rays, and can easily make out the outline of the flashlight.
Spacing at 1. (Default for quality + performance.)
Spacing at .3 . (Default for quality)


My goal is to be able to run many lights + blocks at .3 spacing with little to no performance impact. I'm not too sure if I can, but believe me, I'm working on it. :P
On the video, you can see it running pretty smooth. Yet on the area where I'm shining lights through holes in the wall. I can feel a frame rate decrease. And that's not good obviously. :P


Thanks for reading. : )

Nice lighting system, looks awesome dude!

Nice lighting system, looks awesome dude!

Thanks, also I noticed I got a new rank. :D

hell yes, that lighting system is epic!

:D You know how much we all envy your efforts :D

also my 99 cents is READY! lol

WOO! :D

But put those pennies away good sir because I plan to make this game FA FA FA FREE! XD

WHA WHA WHA???? OH MY GOD, THIS IS THE HAPPIEST DAY OF MY LIFE!!!!!!!!!!!!!!!!!!!! Now... what do I do with these 99 pennies... wait! One more and I can get a soda!

How much would you pay for this ice cold soda? 1000 dollars? 100 dollars? ONE DOLLAR!?!? How about, oh shit. Yeah it's a dollar...

Hey guys, notice any difference?




No?
How about the fact that 15 lights are currently active checking against an area with many blockers still active while maintaining a decent frame rate. :D

Edit:
It's still being worked on as I speak. That's why it looks more shitty. :P
