Hi Guys,
New here, well, lurk a lot, don't post much. A bit shy

Anyway, I am having some trouble with calculations with moving my objects in a 3d space.
The exact object in question is a bullet. If I click, I need it to follow the path until either it exits the map or similar, but the part I am struggling with is setting the speed along the X axis, speed along the Y axis, and speed along the Z axis.
To elaborate further, when the user fires, it must spawn the entity and send it travelling in that direction at it's preset speed.
I hope this makes sense and that you can help please. I am not that great at Trig so have been failing at getting the speed it must go at.
