xna Turret
Author
I’m trying to create c# xna code that will rotate a turret with a mouse. I have not found a code example or anything for this. How is it done?
Edited: I forgot to mention this is a 2d game.
I got the mouseState, however how do I use this to actually aim?
do you want the turret to rotate to face where the pointer is or do you want to the turret to rotate based on the right/left movement of the mouse?
Im no math wizard but i think this will work. Use GetCursorPos() to get the mouse position. Then subtract the Turrets position from it. Like
XYCoord Direction = (MousePos - TurretPos)
I think this will give you the direction the in were the mouse is reletive to the turret.
Hopefully im right and someone can start were i left and tell him how to use this to rotate the turret.
:D

just use atan2 then
the code looks like:
turret.rotation=atan2(mouse.y-turret.y,mouse.x-turret.x)*180/PI
(you might have to subtract 90 from the result of the above calculation to accommodate for the way screen coordinates are handled vs graph coordinates, but it's been a while since I've done it so I've forgotten).
