Rotate Actor

Babulesnik · 01-04-2011 06:23 PM

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.

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!

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

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?

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

llynx · 01-17-2011 06:01 PM

ah so like

Code:

Players[0].angle.set(Players[0].angle.x+0.05f,Players[0].angle.y);
