C# 클래스 XnaFlixel.FlxEmitter

FlxEmitter is a lightweight particle emitter. It can be used for one-time explosions or for continuous fx like rain and fire. FlxEmitter is not optimized or anything; all it does is launch FlxSprite objects out at set intervals by setting their positions and velocities accordingly. It is easy to use and relatively efficient, since it automatically redelays its sprites and/or kills them once they've been launched.

This function generates a new array of sprites to attach to the emitter.

public CreateSprites ( Microsoft.Xna.Framework.Graphics.Texture2D graphics, int quantity ) : FlxEmitter
graphics	Microsoft.Xna.Framework.Graphics.Texture2D	If you opted to not pre-configure an array of FlxSprite objects, you can simply pass in a particle image or sprite sheet.

프로퍼티 상세

delay 공개적으로 프로퍼티

This variable has different effects depending on what kind of emission it is. During an explosion, delay controls the lifespan of the particles. During normal emission, delay controls the time between particle launches. NOTE: In older builds, polarity (negative numbers) was used to define emitter behavior. THIS IS NO LONGER THE CASE! FlxEmitter.start() controls that now!
