862 Chapter 14: Properties

This statement stores a reference to the eighth model of the cast member named 3DWorld in the

variable thismodel.

thismodel = member("3DWorld").model[8]

This statement shows that there are four models in the member of sprite 1.

put sprite(1).member.model.count

-- 4

modelA

Usage

collisionData.modelA

Description

3D collisionData property; indicates one of the models involved in a collision, the other model

being

modelB.

The

collisionData object is sent as an argument with the #collideWith and #collideAny

events to the handler specified in the registerForEvent, registerScript, and

setCollisionCallback

commands.

The

#collideWith and #collideAny events are sent when a collision occurs between models to

which collision modifiers have been added. The

resolve property of the models’ modifiers must

be set to

TRUE.

This property can be tested but not set.

Example

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

#putDetails handler for the #collideAny event. The second part is the #putDetails handler.

When two models in the cast member named MyScene collide, the

#putDetails handler is

called and the

collisionData argument is sent to it. This handler displays the modelA and

modelB properties of the collisionData object in the message window. The third part of the

example shows the results from the message window. These show that the model named

GreenBall was

modelA and the model named YellowBall was modelB in the collision.

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

on putDetails me, collisionData

put collisionData.modelA

put collisionData.modelB

end

-- model("GreenBall")

-- model("YellowBall")
