Recap: Double Jump

Part of the Building Real Games section of Coddy's Unity journey. Lesson 42 of 56.

Challenge

Medium

Write the platformer hero's movement in Hero.cs; the Hero has a CharacterController. The Inspector sets speed (5), gravity (-25), jumpHeight (2) and airJumpHeight (1.28).

The arrows (or WASD), read with the raw axes, walk the hero with controller.Move at speed units a second along x and z.
Gravity by hand: a vertical speed that gains gravity every second, set to -2 while the hero is grounded and falling.
Space on the ground jumps exactly jumpHeight high.
Space in the air jumps once more, rising airJumpHeight above the point where it was pressed. One air jump per time in the air: landing gives it back.

Press Play, double jump onto the ledge, then Check.

Try it yourself

using UnityEngine;

public class Hero : MonoBehaviour
{
    public float speed = 5f;
    public float gravity = -25f;
    public float jumpHeight = 2f;
    public float airJumpHeight = 1.28f;

    CharacterController controller;

    void Start()
    {
        controller = GetComponent<CharacterController>();
    }

    void Update()
    {
    }
}
