Property Details

_world public_oe property

public World _world
return World

maxAcceleration protected_oe property

protected float maxAcceleration
return float

maxInitialSpeed protected_oe property

protected float maxInitialSpeed
return float

maxLifetime protected_oe property

protected float maxLifetime
return float

maxNumParticles protected_oe property

protected int maxNumParticles
return int

maxRotationSpeed protected_oe property

protected float maxRotationSpeed
return float

maxScale protected_oe property

protected float maxScale
return float

minAcceleration protected_oe property

minAcceleration and maxAcceleration are used to control the acceleration of the particles. The particle's acceleration will be a random number between these two. By default, the direction of acceleration is the same as the direction of the initial velocity.
protected float minAcceleration
return float

minInitialSpeed protected_oe property

minInitialSpeed and maxInitialSpeed are used to control the initial velocity of the particles. The particle's initial speed will be a random number between these two. The direction is determined by the function PickRandomDirection, which can be overriden.
protected float minInitialSpeed
return float

minLifetime protected_oe property

minLifetime and maxLifetime are used to control the lifetime. Each particle's lifetime will be a random number between these two. Lifetime is used to determine how long a particle "lasts." Also, in the base implementation of Draw, lifetime is also used to calculate alpha and scale values to avoid particles suddenly "popping" into view
protected float minLifetime
return float

minNumParticles protected_oe property

minNumParticles and maxNumParticles control the number of particles that are added when AddParticles is called. The number of particles will be a random number between minNumParticles and maxNumParticles.
protected int minNumParticles
return int

minRotationSpeed protected_oe property

minRotationSpeed and maxRotationSpeed control the particles' angular velocity: the speed at which particles will rotate. Each particle's rotation speed will be a random number between minRotationSpeed and maxRotationSpeed. Use smaller numbers to make particle systems look calm and wispy, and large numbers for more violent effects.
protected float minRotationSpeed
return float

minScale protected_oe property

to get some additional variance in the appearance of the particles, we give them all random scales. the scale is a value between minScale and maxScale, and is additionally affected by the particle's lifetime to avoid particles "popping" into view.
protected float minScale
return float

particles public_oe property

public Particle[],DodongosQuest.ParticleSystem particles
return DodongosQuest.ParticleSystem.Particle[]

spriteBlendMode protected_oe property

different effects can use different blend modes. fire and explosions work well with additive blending, for example.
protected BlendState,Microsoft.Xna.Framework.Graphics spriteBlendMode
return Microsoft.Xna.Framework.Graphics.BlendState

textureFilename protected_oe property

this controls the texture that the particle system uses. It will be used as an argument to ContentManager.Load.
protected string textureFilename
return string
