I need to make my player constantly point to the mouse, on a 2d plain can someone help me with this?
You can convert your mouse input to a point in world space using the camera screenToWorld() method and then use the entity lookAt() to rotate it to face that point:
There is also this example that does more things, but you can study the part that rotates the player towards the mouse point:
Can you write a script for me that uses the point that updates every 0.2 seconds?
PLEASE, I really need this, to complete my game.
