Hopefully you're not feeling too daunted by the sheer amount of code I have thrown in front of you! I
shall go through it line by line below, the reason I have thrown in so much code is to allow you to run
your Unity application and have your player character move around! If you now click the play button
at the top middle of your Unity interface you should be able to play the game and move your character
quite awkwardly around.
Firstly let's examine our update function:
void Update () {
FindInput();
ProcessMovement();
if (thisIsPlayer == true)
{
HandleCamera();
}
}
We are calling the FindInput function to find out what keys are being pressed and set the variables to
send into the ProcessMovement function to move our character. If we are the player we want to call
HandleCamera and set the camera to follow our player.
void FindPlayerInput ()
{
// find vector to move
inputMovement = new Vector3( Input.GetAxis("Horizontal"),
0,Input.GetAxis("Vertical") );
// find vector to the mouse
tempVector2 = new Vector3(Screen.width * 0.5f,0,Screen.height *
0.5f); // the position of the middle of the screen
tempVector = Input.mousePosition; // find the position of the
moue on screen
tempVector.z = tempVector.y; // input mouse position gives us 2D
coordinates, I am moving the Y coordinate to the Z coorindate in temp Vector and
setting the Y coordinate to 0, so that the Vector will read the input along the X
(left and right of screen) and Z (up and down screen) axis, and not the X and Y (in
and out of screen) axis
tempVector.y = 0;
inputRotation = tempVector - tempVector2; // the direction we
want face/aim/shoot is from the middle of the screen to where the mouse is pointing
