One of my mob's projectiles causes a crash but not every time it shoots. can someone tell me the cause and how to fix? https://pastebin.com/DNbHryF1 ^projectile https://pastebin.com/zsST527J ^error

Thanks! Works perfectly now.

Thanks, but the attacker now takes the damage and the mob does not take any damage. How do I change this? https://pastebin.com/jX8NZV0x ^code

How would I go about making my mob deal damage back to the attacker when hit.

is it not being called in the onUpdate method?

that did not help and I am new to programming mods so do not know how to do everything by myself so am using what is in Minecraft.

https://pastebin.com/Yj00WMsH ^projectile code I just changed the code from EntityLlamaSpit (I have not attempted to add the potion effect here as I am unsure how to)

I don't know how I would do this though.

still does not work https://pastebin.com/iQwGRLdj

I made my entity shoot projectiles and I want the projectile to give poison when it hits. https://pastebin.com/AN9qYw2w ^code

error: https://pastebin.com/5G7Ez1Y9 no crash but it does not spawn

the entity now does not spawn https://pastebin.com/VqNzdBeZ ^EntityPegasus https://pastebin.com/F3dZivKY ^EntityAIAttackRangedBow clone

it does

I get this error: "Bound mismatch: The type EntityPegasus is not a valid substitute for the bounded parameter <T extends EntityMob & IRangedAttackMob> of the type EntityAIAttackRangedBow<T>" https://pastebin.com/aRhGjMZ3 ^code
