930 Chapter 14: Properties

Example

This example has two parts. The first part is the first line of code, which registers the #explode

handler for the

#collideAny event. The second part is the #explode handler. When two models

in the cast member MyScene collide, the

#explode handler is called and the collisionData

argument is sent to it. The first nine lines of the

#explode handler create the model resource

named SparkSource and set its properties. This model resource is a single burst of particles. The

tenth line of the handler creates a model named SparksModel using the model resource named

SparkSource. The last line of the handler sets the position of SparksModel to the position where

the collision occurred. The overall effect is a burst of sparks caused by a collision.

member("MyScene").registerForEvent(#collideAny, #explode, 0)
