Someone could help me.

Thank you very much, I managed to do as you said, and guided by some github repositories EDIT: After trying the mod for a few moments, when it comes to killing an enemy, the game gives me an error "net.minecraft.crash.ReportedException: Exception ticking world" Crash-Report: ---- Minecraft Crash Report ---- // My bad.

Is there a tutorial on that subject? Or do you know of a repository? Thanks for the help

Hi guys, I have a problem assigning extra values to the mobs, I have a capability that assigns them a random value for their size, which is used to render the model of the mob. If I initialize the random size in the capability constructor, every time I want to access it from different events it gives me a different number. On the other hand, if I randomly assign it in the "EntityConstructing" event when I get the capability value in another event, it returns it as if I had not assigned it.
