SET_PARTICLE_FX_LOOPED_EVOLUTION

I've found a way how to find which propertyName available for PTFX.

You need CodeWalker for that.

• Run CodeWalker RPF Explorer

• Search for PTFX dict(eg, scr_ih_sub)

• Open context menu for PTFX dictionary and Export it as XML file

• Open XML file in any text editor and search for desired particle effect(eg, scr_ih_sub_pool_door)

• Then look its internals for EventEmitterFlags property(one property per emitter of PTFX)

• Every Item you will find there is propertyName for Evolution

Here's example for scr_ih_sub_pool_door:
<EventEmitterFlags>

<Item>depth</Item>

</EventEmitterFlags>

where depth is our propertyName.

And here's how it was used in R* scripts(am_mp_nightclub):
void func_3486(var uParam0)

{

uParam0->f_247 = "scr_ih_sub";

uParam0->f_248 = "scr_ih_sub_pool_door";

uParam0->f_250 = { 0.2f, 0f, 0f };

uParam0->f_253 = { 0f, 0f, 0f };

}

void func_3471(var uParam0, int iParam1)

{

if ((!MISC::IS_STRING_NULL_OR_EMPTY(uParam0->f_248) && !MISC::IS_STRING_NULL_OR_EMPTY(uParam0->f_247)) && func_11143(iParam1))

{

GRAPHICS::USE_PARTICLE_FX_ASSET(uParam0->f_247);

uParam0->f_246 = GRAPHICS::START_PARTICLE_FX_LOOPED_ON_ENTITY(uParam0->f_248, iParam1, uParam0->f_250, uParam0->f_253, 1f, false, false, false);

}

}

void func_3453(var uParam0, float fParam1, bool bParam2)

{

float fVar0;

if (bParam2)

{

fVar0 = func_3454(fParam1);

}

else

{

fVar0 = fParam1;

}

if (GRAPHICS::DOES_PARTICLE_FX_LOOPED_EXIST(uParam0->f_246))

{

GRAPHICS::SET_PARTICLE_FX_LOOPED_EVOLUTION(uParam0->f_246, "depth", fVar0, true);

}

}
