OnMouseDown and OnMouseUp not working,onMouseDown not working
This script is added as a component to the Main Camera (which is parented under the Player GameObject) and should take the positions from OnMouseDown and OnMouseUp to generate a Vector2 that applies a fixed ConstantForce2D to the Player in the selected direction for an amount of time. At first, the script was added to the Player GameObject but OnMouseDown would activate only when you pressed over the Player. I tried adding it to the Main Camera and I tried with and without a BoxCollider but it isn't detecting either OnMouseDown nor OnMouseup. Could somebody help me please?
