Rotate Actor
It is necessary to turn the actor.I realise thus

Actor stakan_act;
stakan_act.matrix(Matrix3(stakan_act.matrix().rotateX(tik) )).pos(Vec(0,45,0));

How it is possible to make easier???

stakan_act.matrix().setRotateX(tik); -does not work.

RE: Rotate Actor
I don't really want to start a new topic but this is more or less about matrix's so..
I am trying to rotate my character so it faces the general direction of the screen for my third person camera but right now it "rotates" the character in world space but i want to rotate it locally (like when you press q or e it turns the character).

This is what i have right now: Called in Player::update()

Code:
if(Kb.b(KB_K))
{
    //I don't know where to make use of screendir right now
    //ScreenToPosDir(Vec2(0,0), screenpos, screendir);  

    ctrl.actor.collision(false);
    ctrl.actor.gravity(false);

    //This rotates in world space, how do i rotate the character in local
    //space like pressing Q or E?
    matrix(Matrix(matrix().rotateY(0.001)));
}
I also tried
Code:
matrix(Matrix(matrix().pos,screendir));
matrix(Matrix(OrientP(pos(),screendir,Vec(0,0,1))));
Is there a better way to do this? Thanks!

RE: Rotate Actor
you want to use orientation [.orn()] for that

something like this, you'd have to modify this to work for you

Code:
Orient orientation = Orient(bone->actor.orn());
orientation*=Matrix3().setRotate(orientation.perp.x,0.01f);
bone->actor.orn(orientation)

*Edit* This method works for non-static actors like ragdoll bones

RE: Rotate Actor
Cool, thanks i am going to try it right now


Code:
Players[0].ctrl.actor.orn().asText();
Hmm, this seems to always return
"X: 1.000,0.000,0.000 Y: 0.000,1.000,0.000 Z: 0.000,0.000,1.000" no matter what direction i face.

What am i doing wrong?

RE: Rotate Actor
controller always has the same rotation, only chr::angle is changing
