Make GameObject follow the mouse (non click just more mouse and go in that direction.)

Question

Basicly for movment in my game i want to move the mouse and have the player move and rotate towards mouse position. C#. all have been click to move scripts i have searched on googleyeyes and have not been useful. (not click to move, just follow the direction the mouse is to the screen) fast paced top down game were clicking would hurt gameplay. looking for pointers or tutorials :D was thinking along the lines of "LookAt mouse position"

Answer 1

If you're in top-down 3D LookAt will work. But you'd need to transfer your mouseposition, which is in the 2d coordinate system of your screen into the game world. To do that use
Camera.ScreenToWorldPoint(Input.mousePosition);

The command will return a position in the near clipping plane of the camera (the white rectangle close to the camera in scene view). if you first set the z value of the vector to change, e.g. to 10, the world space vector will be 10 units from the near clipping plane. This approach works for 0° views onto the game scene if you know the distance from camera. If you're looking at an angle however you would need to raycast into the scene to get a point on the ground (Use Camera.ScreenPointToRay and Physics.Raycast for that) In either case, set the "up component of that vector", relative to the player, to its center y position. Now you have a vector that is at the same level as the player and it can look at it and move towards it.

HINT: I know, that in the beginning one just wants something to work, but will get even more frustrated when it gets harder and one didn't even understand what the codes they copied from the internet did... Write one yourself.
