Conditions allow your games to react to events. Do you want to know whether a missile hits one of your aliens? Or when a baddie has moved off the screen? There’s a condition for all situations. Once Klik & Play has tested for a condition, it can then perform an appropriate action in your game.
What is a condition?
Klik & Play’s main task during a game is to keep checking a list of events, over and over again. When any of these events becomes “True”, the actions associated to it will be made to happen.
An event consists of one or more conditions. If an event has several conditions, then all the conditions have to be “True” before the actions can happen.
Here’s an event that checks for a character picking up an extra life bonus and ensuring that the total number of extra lives doesn’t run over 5:
| Event | Actions |
| [Romeo] Collides with [Extra Life] | Destroy Extra Life |
| Number of lives of [Player1] < 5 | Add 1 to number of Lives |
