Jump Pads

Design

Implementation

Jump pads are obstacle entities that temporarily increase the player's jump height after/while colliding with it. The obstacles will be placed around the map, mainly in sections of the map that are built to require a higher jump height, as a sort of non-pick-up-able power up.

To implement this, the JumpPadComponent class was created. JumpPadComponent is a dummy component that from extends JumpableComponent to act as an indicator to the onCollisionStart function in the PlayerMovementComponent class to whether the player has hit a jump pad. onCollisionStart has been modified to deal with the interactions between the player and the jump pads in that if the fixture of the specified targetLayer (i.e. obstable) has a JumpPadComponent, the jumpPad() function in PlayerActions is called. This applies a force to the player's body as defined as the jumpPadSpeed. Currently, it is double the current jumpSpeed of the player.

if (jumpPadComponent != null) {
        // Colliding with jumppad
        playerActions.jumpPad();
   }

public void jumpPad() {
    body.applyForceToCenter(jumpPadSpeed, true);
   }

Additionally, it is intended that collision with the jump pad will trigger an animation of the jump pad in order to visually indicate the behavior of the obstacle to the user. This is scheduled to be implemented in a future sprint.
