So I have a custom entity and almost everything is fine with it. It can be ridden and moved, but when it does, the parts don't rotate. Everything rotates fine when it is not being ridden. Here is the code for the mob.

 

EntityElephant.java

package com.ctwagon.testmod.entity.mobs;

I don't know what the issue is, but if you copy vanilla classes, you MUST remove the 

__OBFID

lines, as that will screw up the building of the mod and make it not work.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.
