Topic awaiting preservation: Raycasting engine with dynamic lighting. (Page 1 of 1)

http://www.elephantsneverforget.co.uk/SKYNET/lighting.html

Use wasd to move around. This map has two lights one (behind you when you start) is moving around.

It's a little slow (if you disable light collision detection it's quite fast though, even on my crappy computer), if you put the light precision to 8 it's less glitchy but slows down to about 5fps with me


Anyone got any ideas on speeding it up or improving the blending / lighting parts?

The poster has demanded we remove all his contributions, less he takes legal action.
We have done so.
Now Tyberius Prime expects him to start complaining that we removed his 'free speech' since this message will replace all of his posts, past and future.
Don't follow his example - seek real life help first.

Nice stuffola there !! My suggestions are guesses more than fact based.
--------------------------------------------------------------------------

WallSlices[X]=document.createElement("DIV");
WallSlicesXstyle = WallSlices[X].style;

then: (don't know if this will speed up or not)

WallSlicesXstyle.position="absolute";
WallSlicesXstyle.height=Height;
WallSlicesXstyle.top=(100-(Height>>1));
WallSlicesXstyle.left=(X<<3);
WallSlicesXstyle.backgroundColor=Color;
WallSlicesXstyle.width=8;
//WallSlicesXstyle.zIndex=-z;
----------------------------------------------------------------------------
above the loop: ( don't know if this is safe or not )
pcontainer = document.getElementById("container"); //do once above loop?

then in the loop:
p.appendChild(WallSlices[X]);
----------------------------------------------------------------------------

before:
document.getElementById("obj"+i).style.left=transx - (height>>1);
document.getElementById("obj"+i).style.width= (height>>2);
document.getElementById("obj"+i).style.height= (height>>2);

after:
pobjstyle = document.getElementById("obj"+i).style;
pobjstyle.left=transx - (height>>1);
pobjstyle.width= (height>>2);
pobjstyle.height= (height>>2);
