Reimplemented from GameBaseData.

void ParticleEmitterData::packData ( BitStream * stream ) [virtual]

Reimplemented from SimDataBlock.

void ParticleEmitterData::unpackData ( BitStream * stream ) [virtual]

Reimplemented from GameBaseData.

bool ParticleEmitterData::preload	(	bool	server,
		String &	errorStr
	)			`[virtual]`

Called to prepare the datablock for use, after it has been unpacked.

Parameters:

	server	Set if we're running on the server (and therefore don't need to load things like textures or sounds).
	errorStr	If an error occurs in loading, this is set to a short string describing the error.
