It is no secret players love to get powered up in a game. In Shoot-em-up games, for example, this will mean more powerful shot, speed boost, temporary shield, super missiles and any crazier weapons/movement you can think of.
Activating powerup
Powerups are usually activated temporarily when players collect or collide with some sort of powerup game objects
Shot powerup:
Now add a speed boost powerup:
And the one below is my favorite Protective Shield power-up:
As you can see, adding power-up one at a time is straight forward. It is only limited by your imagination and design. It is worth noting, however, that game logic can become complicated if
- different powerups can be activated and combined at the same time.
- each type of power-up can have further level-up, for example, collecting speed-boost multiple times can let the player move faster and faster.
- To avoid too many or too few power-up on the screen, additional logic may also be needed.
- Some power-up could be too powerful and the game can only spawn them under some special conditions.
