I just had an idea, in games like WoW and Terraria, when ever you damage a target a number pops by the character showing how much damage that hit has inflicted. This could be implemented into Blockland fairly easily I would think. All you would need to do is make a script to spawn a different pain emote for every health point between 0 - 100. Maybe you would not even have to use pain emote.
What do you think? I just thought that could be useful for RPGs and such.
