Tutorial
1. Go to 'accessory manipulation' and click 'load'.
2. Select 'ActiveParticleFire.x' and click 'OK'.
Accessory Parameter Values
-X, Y, and Z: Adjusts the position of the effect.
-Si: Adjusts the amount of particles generated.
-Tr: Adjusts the opacity of the particles.
Editing the Code Parameters
-Line 10: #define UNIT_COUNT: Determines the maximum number of particles, by multiples of 1024, that can be generated at once. Setting this value to 1 sets the maximum number of particles to 1024, or (1 x 1024); whereas setting it to 4 sets the maximum to 4096, or (4 x 1024).
-Line 12: float ParticleSize: Determines the size of the particles.
-Line 13: float ParticleSpeedMax: Determines the maximum initial speed of the particles generated.
-Line 14: float ParticleSpeedMin: Determines the minimum initial speed of the particles generated.
-Line 15: float ParticleInitPos: Determines the initial position where particles spawn, relative to the accessory x file.
-Line 16: float ParticleLife: Determines the duration of the particles generated, represented in seconds.
-Line 17: float ParticleDecrement: Determines when the particles begin to disappear, represented as a ratio to ParticleLife. A smaller value means the particles will disappear sooner.
-Line 18: float OccurFactor: Determines the number of particles generated relative to the movement. A greater number means more particles are generated.
-Line 19: float ObjVelocityRate: Determines the particle velocity relative to the accessory x file's movement speed.
-Line 21: #define FireColorTexFile: Determines which image file to use when generating the color of the flames.
-Line 24: float fireDisFactor: Determines the maximum distance the flame can flare out to. A larger number means the flame will not flare out as far.
-Line 25: float fireSizeFactor: Determines the maximum size the flame can flare out to. A larger number means the flame will flare to a larger size.
-Line 26: float fireShakeFactor: Determines the speed at which the flame flares. A larger number means the flame will flicker more frequently.
-Line 28: float fireRiseFactor: Determines the maximum height the flame can reach.
-Line 29: float fireWvAmpFactor: Determines the range intensity of the flame's sideways fluctuations.
-Line 30: float fireWvFreqFactor: Determines the frequency of the flame's sideways fluctuations.
-Line 32: int FrameCount: Determines the frequency at which the flame texture is updated. Setting this value to 1 updates it every 60 frames; 2 updates it every 30 frames, and so forth.
-Line 34: float3 GravFactor: Determines the intensity of gravity on the particles generated, represented in a (x, y, z) format.
-Line 35: float ResistFactor: Determines the velocity resistance of the particles generated. A greater value means the particles will drag along.
-Line 43: float3 vel = float3: Determines the initial velocity of the particles generated. A non-zero value means the particles will be generated even when the accessory x file is not being moved.
Tips
-You can attach the effect to a model's bone and it will follow the bone movement.
-Harigane recommends setting this effect to be at the bottom of the accessory draw order.
-As the frame rate affects the fire effect, Harigane recommends setting the FPS refresh rate in line 32 of the code, and then loading in the effect.
-By default, the maximum number of particles generated will not exceed 4096. The effect will stop generating new particles until some have disappeared.
-The amount of particles generated is determined by the movement distance, ie. moving the effect a shorter distance will produce fewer particles than moving the effect a farther distance.
