Lab 3 - Player Control

Regardless of what type of movement your player has, it’ll definitely need a PlayerController script

1. Select your Player and add a Rigidbody component (with or without gravity enabled)
2. In your Assets folder, create a new “Scripts” folder
3. Inside the new “Scripts” folder, create a new “PlayerController” script
4. Attach it to the player, then open it
5. Determine what type of programming will be required for your Player

By the end of this step, you should have a new Script open and a solid plan for what will go in it.

The first thing we’ll program is the player’s very basic movement based on user input

1. Declare a new private float speed variable
2. If using physics, declare a new Rigidbody playerRb variable for it and initialize it in Start()
3. If using arrow keys, declare new verticalInput and/or horizontalInput variables
4. If basing your movement off a key press, create the if-statement to test for the KeyCode
5. Use either the Translate method or AddForce method (if using physics) to move your character

By the end of this step, the player should be able to move the way that you want based on user input.

No matter what kind of movement your player has, it needs to be limited for gameplay

1. If your player is colliding with objects they shouldn’t (including the ground), check the “Is trigger” box in the Collider component
2. If your player’s position or rotation should be constrained, expand the constraints in the Rigidbody component and constrain certain axes
3. If your Player can go off the screen, write an if-statement checking and resetting the position
4. If the Player can double-jump or fly off-screen, create a boolean variable that limits the user’s ability to do so
5. If your player should be constrained by physical barriers along the outside of the play area, create more primitive Planes or Cubes and scale them to form walls

By the end of this step, the player’s movement should be constrained in such a way that makes your game playable.

Now that we have the basic functionality working, let’s clean up our code and make a backup.

1. Create new Empty game objects and nest objects inside them to organize your hierarchy
2. Clean up your Update methods by moving the blocks of code into new void functions (e.g. “MovePlayer()” or “ConstrainPlayerPosition()”)
3. Add comments to make your code more readable
4. Test to make sure everything still works, then save your scene
5. Right-click on your Assets folder > Export Package then save a new version in your Backups folder

By the end of this step, your code should be commented, organized, and backed up.
