[Solved]Decals and wheel trace

Hello,

I'm trying to add wheels traces by using decals and I have a little question about drawing my traces.

As you can see some decals are extended or narrowed. I've checked tutorial and I saw thet when I shot between barrel and ground I have similar effect:

This is part of code which create decals:

Code:

Game::World.terrainAddDecal(WHITE,Materials.ptr("Gfx/Trace/Trace.mtrl"),wheel[2].matrix());

Is here something wrong?

Problem aboive is solved.

How can I rotate decals which I put on the terrain? I tried some transformations with matrix but it doesn't help.

setting correct matrix should do the trick

1st code:

Code:

Game::World.terrainAddDecal(WHITE,Materials.ptr("Gfx/Trace/Trace.mtrl"),Matrix().setRotateY(T.matrix().angles().y).move(T.wheel[2].matrix().pos-Vec(0,0.2,0)).scaleOrn(0.3f));

2nd code:

Code:

Game::World.terrainAddDecal(WHITE,Materials.ptr("Gfx/Trace/Trace.mtrl"),Matrix().setPosDir(wheel[3].matrix().pos-Vec(0,0.2,0),Vec(0,1,0)).scaleOrn(0.3f));

In the first code as you can see traces isn't draw properly but they are rotating. In the second code I tried many ways to rotate this but I failed. Could someone give me an advice?

Well maybe u can try it with Lerp() so it interpolates between 2 decals.

But what i think about your first code.. its looks like it that the decals turns in the wrong direction.

Thank you Dynad for give me a clue. I rotate decals in y axis by 90 degrees and now they are drawing ok smile
