Thank you for your assistance!
I have another question. Currently, I am trying to reference 'EntityPlayer' and 'EntityPlayerSP'. This is the code for 1.8.9:
protected final net.minecraft.client.entity.EntityPlayerSP player;
if (player.isUsingItem()) {
// do something
}
// elsewhere in code
if (player.movementInput.jump) {
player.sendQueue.addToSendQueue(new CPacketEntityAction(...));
}
This approach, however, doesn't seem to contain the either sendQueue or isUsingItem. I tried checking around for any other ItemStack objects (for isUsingItem), and found itemStackMainHand, however this doesn't sound like what I would want. Would you know what fields they are now?
