Question by martipello · Oct 29, 2017 at 08:32 PM · particlesystemsizefloatcurvelifetime

modify particle system startLifetime over time

Im trying to reduce the size of a flame I've made with a particle system, I need it to get smaller over time without affecting its style or the parent scale, the best option I thought is to change the startLifetime of the particle system which does work brilliantly, but trying to do this at run-time isn't working. I can get the particle system main module and assign a float to it and the value is updated and works fine but if I try to compare against it or update it over time i get an error that Operator > (or-=)' cannot be applied to operands of type UnityEngine.ParticleSystem.MinMaxCurve' and `float', so how come i can set a float to it but can't compare it against a float? what am i missing? heres the code

        if(main.startLifetime > psSizeMin){
             main.startLifetime -= reduceHealth * Time.deltaTime;  //reduce size
         }

sorry fixed it

     float size = main.startLifetime.constant;
         if(size > psSizeMin){
             size -= reduceHealth * Time.deltaTime;  //reduce size
             main.startLifetime = size;
         }
