Hi !
I'm trying to create particle systems from code, using a factory from a
file... I've tried many combinations, but I'm lost.
How to do that ?
The following code fails on getting iParticleState:
csRef<iMeshFactoryWrapper> factoryw = loader->LoadMeshObjectFactory (
"/xd/models/thrusterparticles");
if (!factoryw)
return ReportError ("Unable to load thrusterparticles!");
// Initialize the emitter mesh object(s) used for thruster(s).
emitters.Empty ();
size_t i = 0;
csString pattern;
keybase = cfgkey + "ThrusterUnit.";
while (config->SubsectionExists (pattern.Format (keybase + "%d.", i)))
{
ThrustersInfos* infos = new ThrustersInfos (); // a csObject
/* that doesn't work neither
csString meshname;
infos->meshw = engine->CreateMeshWrapper (factoryw,
meshname.Format ("ThrusterEmitter%d", i),
pccamera->GetCamera ()->GetSector (),
csVector3 (0.0f, 0.0f, 0.0f));
*/
infos->meshw = factoryw->CreateMeshWrapper ();
if (!infos->meshw)
return ReportError ("Unable to create particle meshwrapper!");
///engine->AddMeshAndChildren (infos->meshw);
//infos->SetName (meshname.GetData ());
// is messing with iMeshObject really needed ?
csRef<iMeshObject> meshobject =
factoryw->GetMeshObjectFactory ()->NewInstance ();
infos->meshw->SetMeshObject (meshobject);
engine->AddMeshAndChildren (infos->meshw);
infos->state = SCF_QUERY_INTERFACE (infos->meshw->GetMeshObject (),
iParticleState);
if (!infos->state)
return ReportError ("Unable to get iParticleState!");
[...]
just in case:
