here an example code of an entity looking at the player constantly. Everything works fine and here. (a bit slow but ok):
action look_at_player()
{
while(1)
{
VECTOR temp_vec;
ANGLE temp_angle;
ANGLE head_angle;
vec_set(temp_vec,player.x);
vec_sub(temp_vec,my.x);
vec_to_angle(temp_angle,temp_vec);
vec_sub(temp_angle, my.pan);
//head
head_angle.pan = temp_angle.pan;
head_angle.tilt = temp_angle.tilt;
head_angle.roll = 0;
head_angle.tilt = clamp(head_angle.tilt, -80, 80);
head_angle.pan = clamp(head_angle.pan, -90, 90);
ent_bonereset(my,"Head");
ent_bonerotate(my,"Head",head_angle);
wait(1);
}
}
But now I don`t only need the head to rotate, but also the (lets say) right arm and left arm. Then it would look like this;
action look_at_player()
{
while(1)
{
VECTOR temp_vec;
ANGLE temp_angle;
ANGLE head_angle;
ANGLE right_arm_angle;
ANGLE left_arm_angle;
vec_set(temp_vec,player.x);
vec_sub(temp_vec,my.x);
vec_to_angle(temp_angle,temp_vec);
vec_sub(temp_angle, my.pan);
//head
head_angle.pan = temp_angle.pan;
head_angle.tilt = temp_angle.tilt;
head_angle.roll = 0;
ent_bonereset(my,"Head");
ent_bonerotate(my,"Head",head_angle);
//right arm
right_arm_angle.pan = temp_angle.pan;
right_arm_angle.tilt = temp_angle.tilt;
right_arm_angle.roll = 0;
ent_bonereset(my,"right_arm");
ent_bonerotate(my,"right_arm",right_arm_angle);
//left arm
left_arm_angle.pan = temp_angle.pan;
left_arm_angle.tilt = temp_angle.tilt;
left_arm_angle.roll = 0;
ent_bonereset(my,"left_arm");
ent_bonerotate(my,"left_arm",left_arm_angle);
wait(1);
}
}
And that is a real fps killer. Is there any way to save fps in that example? I needs alot more ghosts to stop this fps packman!

Try this and see if it makes a difference in FPS...
action look_at_player()
{
ANGLE temp;
while(1)
{
vec_sub(vec_set(temp, player.x), my.x);
vec_to_angle(temp, temp);
vec_sub(temp, my.pan);
//head
ent_bonereset(my,"Head");
ent_bonerotate(my,"Head", vector(temp.pan, temp.tilt, 0));
//right arm
ent_bonereset(my,"right_arm");
ent_bonerotate(my,"right_arm", vector(temp.pan, temp.tilt, 0));
//left arm
ent_bonereset(my,"left_arm");
ent_bonerotate(my,"left_arm", vector(temp.pan, temp.tilt, 0));
wait(1);
}
}

Every time you move a bone you're also updating every vertex attached to that bone (and any attached to children of that bone). By default GS does this on the CPU, but you can look at matBones to find a much faster alternative -- the vertices are only moved in the shader (GPU is much better suited to this kind of thing), but it means if you use vec_for_vertex or something similar you won't get the correct position.
I love matBones. It makes a huge difference to performance with bones-animation.

JippSmart, could you show me how you would use "matBones" to solve this FPS problem?
