##### Rotation towards movement direction but with translating movement [SOLVED]
« on: May 30, 2019, 03:56:39 AM »
Hi all,

i'm trying to find a solution for rotating some missiles towards direction.

After they're being fired they are moved using translate with no set target. I'm not using velocity so i can't get the direction with velocity data (it's 0,0 since i'm translating the missiles), and i don't know how can i get the direction every frame to apply the rotation by using some other method.

All ideas except "move them using velocity" are welcome

Edit: of course, the child will be rotating so it doesn't affect the movement.

I was just wondering, if i get the current position and last frame position, and subtract current from last frame position i should be getting the vector that shows the missile's heading. How can i apply that vector to the rotation of the child object?

Or maybe simply rotate towards last frame position but in opposite direction, hmmm.

Got it the simple way. Get position, look at with 180 degree offset in the next state, loop.
