Algodoo

Search scenes and forum for the word "texturematrix".

yeah, I know, but can I reverse the: higher the value the smaller it gets to higher the value the higher it gets in a way I can do something similar to the size/distance?

Here is the textureMatrix array in a nutshell:

[Xscale,Xrotation,Xoffset,Yrotation,Ysc­ale,Yoffset,0,0,0]

The last three zeros in the array are not used, or I simply do not know what they are for. They don't seem to have any effect when I make them other than zero. They may be there for some future use if/when Algodoo gets updated.

Here is how to automatically adjust the texture X and Y scale as a box or a circle changes in size.
For a box: [1/size(0),Xrotation,Xoffset,Yrotation,1/size(1),Y­offset,0,0,0]
For a circle: [1/radius,Xrotation,Xoffset,Yrotation,1/radius,Yof­fset,0,0,0]

If you add those calculations directly in the textureMatrix data area then you need to place curly brackets on each side of the array like this:
{[1/size(0),Xrotation,Xoffset,Yrotation,1/size(1)­,Yoffset,0,0,0]}

When resizing a polygon, the calculations for auto-resizing the texture are much more complex which I don't know how to do.

When I put this script in onlaserhit but the texture becomes invalid.

v = math.vec.dist(e.pos, pos);
c = e.geom.texturematrix;
d = [0.02, 0.5 / math.vec.dist(e.pos, pos)];
scene.addbox({
size := [0.02, 0.5 / math.vec.dist(e.pos, pos)];
pos := [scene.my.screenpos(0) + _a - rotation, scene.my.screenpos(1)];
color := e.geom.color;
density := ∞;
collideset := 0;
timeToLive := 0.05;
drawborder := false;
texture = e.geom.texture;
texturematrix = {
[c(0) / d, c(1), e.geom.angle - rotation, c(3), c(0) / d, c(5), c(6), c(7), c(8)]
}
})
do you know what's wrong?

nvm I got it to work.
