Package rekit.logic.gameelements.particles

Class Particle

java.lang.Object

rekit.logic.gameelements.GameElement

rekit.logic.gameelements.particles.Particle

All Implemented Interfaces:

Collidable

Direct Known Subclasses:

DamageParticle, TextParticle

public class Particle
extends GameElement

A simple GameElement with no collision and only with graphical effects. Every Particle has a fixed lifeTime after which it removes itself.

Sad life.

Can be given many options as to how to draw the particle and how it changes these options over time.

Constructor Details

Particle

public Particle()

Create a particle.

Method Details

setProperties

public void setProperties(Polygon polygon,
 Vec pos,
 long lifeTime,
 Progress scale,
 Progress speed,
 Progress rotation,
 Progress angle,
 Progress colorR,
 Progress colorG,
 Progress colorB,
 Progress colorA)

Saves all ProgressDependencies required for the Particle behavior.

Parameters:

polygon - the shape that the particle should be drawn with

pos - the initial position of the particle

lifeTime - the time in millis for how the particle will be rendered

scale - the ProgressDendency for the polygons size

speed - the ProgressDendency for the polygons movement speed

angle - the ProgressDendency for the polygons movement angle

colorR - the ProgressDendency for the polygons red color channel

colorG - the ProgressDendency for the polygons green color channel

colorB - the ProgressDendency for the polygons blue color channel

colorA - the ProgressDendency for the polygons alpha color channel

rotation - the ProgressDendency for the polygons rotation

logicLoop

public void logicLoop()

Description copied from class: GameElement

Template method that will be called periodically after being added to a IScene.

Should be overwritten in sub classes for implementing custom logic, physics emulation, time-based actions, ...

Overrides:

logicLoop in class GameElement

internalRender

public void internalRender(GameGrid f)

Description copied from class: GameElement

Template method that will be called periodically after being added to a IScene. Must be as performant as possible to keep the FPS low, since it will be called in every render-loop.

Should be overwritten in sub classes for custom visualization using the GameGrid.

Overrides:

internalRender in class GameElement

Parameters:

f - the GameGrid that represents the games field and supplies primitive drawing operations.

capColor

public int capColor(float col)

Caps a color to make sure it is never smaller than 0 or greater than 255.

Parameters:

col - the color value to cap

Returns:

the capped color

create

public Particle create()

Create a particle.

Returns:

a new particle
