Open sue's workshop. Open a map with life capsules. Click entity mode. Click the life capsule. Look at the top where it shows the entities event # and sprite #. Profit.
...I did not think of that because I am a moron. Sorry.
Edit: Hmm...That didn't work. I listed the Health Container, Sprite 32, with all the same settings for another one elsewhere, but it just makes a weird sound. I even tried c/ping the script, but that didn't work either. I hope I'm not bothering anyone.
