Hi,

I’ve been trying to look this up but not had any luck so far. I’m trying to make a simple pseudo-3D app, but I’m stuck on how to pull off the movement. If I have an object with x,y,z coordinates, and its movement speed, pitch, and yaw, what formula would I use for movement? So for example, if the object is at 0,0,0, moves 6 units per frame, and has pitch 30 degrees and yaw 15 degrees, what will be its coordinates next frame?

I’ve used the sin/cos/atan formula to move an object along a heading in 2D space, but I’m not sure how to translate this to 3D. I’ve never been great with trig \>\_\<

Much appreciated.
