Have the client send a chat message to self without sending it to the server?
[solved]
All I want to do is force the player to left click (from the client side - that also sends the packet to the server JUST as if I would have done it myself).
Minecraft.getMinecraft().playerController.clickBlock(Minecraft.getMinecraft().objectMouseOver.blockX, Minecraft.getMinecraft().objectMouseOver.blockY, Minecraft.getMinecraft().objectMouseOver.blockZ, Minecraft.getMinecraft().objectMouseOver.sideHit);
thought this line of code would punch the block currently in view, but I tried it out and nothing works D: please help
