I tried my best. PLEASE HELP ME

Here's the explaination:

Full command:
/data modify entity @e[type=witherstormmod:command_block,limit=1] BossfightManager:{PhaseTicks:0} set value 20

It says:"Nothing changed. These attributes alreade have such values."

Nah, ill reopen it just to let the one & the only @nonamecrackers2 know about it.

Closing this since its neither a bug report nor a feature request.

I’m not sure, try removing the “:0” from “PhaseTicks”. This isn’t a help forum though however so I will be closing this

ok
