UDF-dpm
 
Hi I have an easy question. I have a simple code.As: #include "udf.h" DEFINE_DPM_SCALAR_UPDATE(PARTICLEM,c,t,initializa, p) {

if(p->state.pos[0]>0.5)

{

p->stream_index=-1;

}

else

{

} } I expect it removes particle in a 2d rectangular after x>0.5.But when i go to Display-particle Tracks- shows my particle. Incredibly as i do not use (if statement) it works and delete my particle.I am sure that i compile and hook it truely. Please help me ASAP. arh1384@gmail.com Best Regards

I have used P_POS(p)[i] for particle position (i=0 for x etc.) Not sure why your version wouldn't work.

Thank you. Also i used P_POS(p)[i] and it does not work too. Incredible.

Hi I did not use the scale truely. I forgot that all units in UDF is meter. Thank you again
