[1.12.2] Why playerController.attackEntity doesn't work sometimes?

[ykozxy]

I'm currently using the following code segment to simulate a player attacking an entity (basically auto attack).

Minecraft mc = Minecraft.getMinecraft();
mc.playerController.attackEntity(mc.player, mob);

where mob is an instance of EntityLiving.

The mod works well when playing locally, but when on servers (especially those with RPG game mode), sometimes the targeted entity won't get hurt when executing the statement. 

Does anybody know why it is and how can I modify my code?

Why are you doing this on the client side?

A better way would be to implement such interactions on the server side.

Well, I can implement it on the server side, but I'm just confused about the mechanism of the method.

AFAIK some server plugins check whether players' actions are valid, and cancel the actions if they are too... abnormal.

You would be better off to just implement the whole mechanic on the server; this will save a lot of hassle.

Haha thanks, I'll try it.
