on prepareFrame

Syntax

on prepareFrame
	statement(s)
end

Description

System message and event handler; contains statements that run immediately before the current frame is drawn.

Unlike beginSprite and endSprite events, a prepareFrame event is generated each time the playback head enters a frame.

The on prepareFrame handler is a useful place to change sprite properties before the sprite is drawn.

If used in a behavior, the on prepareFrame handler receives the reference me.

The go, play, and updateStage commands are disabled in an on prepareFrame handler.

Example

This handler sets the locH property of the sprite that the behavior is attached to:

on prepareFrame me
	sprite(me.spriteNum).locH  = the mouseH
end
