No life

I made a new element POSP(https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=16558).
When I draw in pause it works, bu if I unpause it disappears.
This is the code:
#include "simulation/Elements.h"
//#TPT-Directive ElementClass Element_POSP PT_POSP 170
Element_POSP::Element_POSP()
{
Identifier = "DEFAULT_PT_POSP";
Name = "POSP";
Colour = PIXPACK(0xDC143C);
MenuVisible = 1;
MenuSection = SC_GAS;
Enabled = 1;
Advection = 0.9f;
AirDrag = 0.04f * CFDS;
AirLoss = 0.97f;
Loss = 0.20f;
Collision = 0.0f;
Gravity = -0.1f;
Diffusion = 0.30f;
HotAir = 0.001f * CFDS;
Falldown = 0;
Flammable = 0;
Explosive = 0;
Meltable = 0;
Hardness = 0;
Weight = 1;
Temperature = 10000.0f +273.15f;
HeatConduct = 5;
Description = "Positive plasma.";
State = ST_NONE;
Properties = TYPE_GAS|PROP_LIFE_DEC|PROP_LIFE_KILL;
LowPressure = IPL;
LowPressureTransition = NT;
HighPressure = IPH;
HighPressureTransition = NT;
LowTemperature = ITL;
LowTemperatureTransition = NT;
HighTemperature = ITH;
HighTemperatureTransition = NT;Graphics = &Element_POSP::graphics;
}//#TPT-Directive ElementHeader Element_POSP static int graphics(GRAPHICS_FUNC_ARGS)
int Element_POSP::graphics(GRAPHICS_FUNC_ARGS){
int caddress = restrict_flt(restrict_flt((float)cpart->life, 0.0f, 200.0f)*3, 0.0f, (200.0f*3)-3);
*colr = (unsigned char)ren->plasma_data[caddress];
*colg = (unsigned char)ren->plasma_data[caddress+1];
*colb = (unsigned char)ren->plasma_data[caddress+2];
*firea = 255;
*firer = *colr;
*fireg = *colg;
*fireb = *colb;
*pixel_mode = PMODE_GLOW | PMODE_ADD; //Clear default, don't draw pixel
*pixel_mode |= FIRE_ADD;
//Returning 0 means dynamic, do not cache
return 0;
}Element_POSP::~Element_POSP() {}

I copied the whole code from PLSM so I don't know
-
It might be worse than that...it looks like life was not defined in this scope. So it can't have any life and the code simply fails.
-
But why is PLSM working?
-
In src/simulation/Simulation.cpp, find the create_part function.
In that function, find the code that sets the default properties for PLSM when PLSM is created.
case PT_PLSM:
parts[i].life = rand()%150+50;
break;Add something similar nearby for your element (or just add "case PT_POSP:" at the start of the code above to give your element the same default properties as PLSM).

It works, thanks
