A concept I wanted to try when decals were implemented. See the video demonstrating it. Here is the script:
HasPlayer [Health] [=<60%]
If you want to use or modify this script be sure to give me credit
This bleeding system would be great for pvp, open world survival servers and hunger games servers but the downside is that you would have to clean up the blood after. I'm thinking of making mobs bleed but I have no idea how to do that.
