gzd-metaparticles
A small helper class intended to make managing particle effects easier.
Usage
The MetaParticle abstract base class provides one property and two virtual functions:
MetaParticle.MaxParticles <int>- Number of particles to allocate and iterate.virtual void ParticleInit(MetaParticleData p, bool first)- Initialization performed whenever a particle is created.bool first- True if this is the first time the particle is initialized. useful for "pre-filling" looping effects to avoid pulsing effects.
virtual void ParticleUpdate(MetaParticleData p)- Code here is applied each particle in the array every tic. This is where the bulk of the effect code can be placed.
The MetaParticleData class is NOT meant to be used directly. When accessed from one of the above virtual functions it has the following members which can be modified:
double size- Size of the particle.double alpha- Alpha value0-1.color col- May be hexadecimal or predefined like "white."int life- Lifetime in ticks.vector3 pos- Position with(x, y, z).vector3 vel- Velocity with(x, y, z).bool bright- Renders the particle fullbright.
Please see the examples.zsc file for two simple effects: MPSnow and MPFire. These may be tested ingame using the summon console command.
