Hi all,
When copying (DEEP_COPY_ALL) the ExplosionEffect, I end up with the
runtime error about pure virtual function call. Debugging shows that
the complaint arises when ParticleEffect::setUpEmitterAndProgram()
is called at copy construction of ExplosionEffect (involved code
excerpts below):
ExplosionEffect::ExplosionEffect(
const ExplosionEffect& copy, const osg::CopyOp& copyop)
: ParticleEffect(copy,copyop)
{
}
ParticleEffect::ParticleEffect(
const ParticleEffect& copy, const osg::CopyOp& copyop)
: osg::Group(copy,copyop),
// Sets several member variables ...
{
if (_automaticSetup) buildEffect();
}
void ParticleEffect::buildEffect()
{
setUpEmitterAndProgram();
// Other code ...
}
Am I doing something wrong by trying to DEEP_COPY_ALL the
ExplosionEffect (or other kind of ParticleEffect)? Should ParticleEffect
in this copy-constuct situation call ExplosionEffect::
setUpEmitterAndProgram()? Your insight is much appreciated.
Thanks,
Sinisa
