[1.8.9] Game Crashes when trying to spawn custom particle

[Spyeedy]

My game crashes when it tries to spawn my custom particle. From what I can tell of my crash reports, the crashing has got something to do with my rendering of my particle. What I am trying to render is lines like Flash's lightning trail.

Hi

 

That crash usually happens when you've tried to use WorldRenderer before .begin().

 

I'm not sure why that's happening in your case because I thought that EntityFX are always called with .begin() already set.

 

It might be because you are calling tes.draw(), which EntityFX normally don't do in their render.

 

-TGG

 

PS an example of a custom EntityFX renderer is here; it might help to understand what the parameters for renderParticle mean.

Look at the "FlameFX" class in mbe50 package

I see, I will try with the new understanding of the parameters of the renderParticle and see if removing tes.draw() works,
