Game Objects

Paddle

BP_Paddle is the player of the game. It handles player input for movement in the horizontal direction. It also handles the Ball Launch Mode: a moving arrow indicating the initial direction of the ball to launch. And it support the firing of lasers if the player has Laser Ammo.

The blocks can be easy set up using the Block Type Enumeration in combination with the DataTable.

Ball
