This mod is a useful API tools for MCreator modders! (This mod is also an API for my minecraft mods) Why? How?

It adds "Impact Wave" which is basically an attack wave that causes the block on the ground to flew up! Note: It can damage entities OR player along the way. (useful as a custom attack for player or mobs!)
Stun Effect: Stun a player for [how many seconds do you want]
mores coming soon (give me suggestions in the comments)

How to use the Impact Wave?

1.) Give the custom mob/boss you made a tag called "owner". (How? : choose a procedure called "execute command [] in the name of event/target entity" AND put this command inside - /data merge entity @s {Tags:["owner"]} - (put it in On initial entity spawn OR Entity Tick Update) )
2.) Summon the Impact Wave (How? : choose a procedure called "execute command [] in the name of event/target entity" AND put this command inside - /summon dreamcaslib:impact_wave ^ ^ ^1[Or the number you want. Note: the number is how far away the impact wave is going to be summon...] (Put this in the procedure of the mob/boss you wanted.
