Using Mcreator to code very specific behaviors...

Hi!

I'm very new to mcreator, and while I've gotten the hang of some aspects of it, I need more qualified input on a project of mine.

I've built a biome, blocks, a few items, etc. all to my current satisfaction, but I'm facing a stumbling block (haha) when it comes to programming the main mob I'm working on.

I don't know where to begin, so let's start with the behavior I want to create...

(I already have a model, texture, and animations by the way):

I'd like for my creature to behave like a breeze, but with some key differences.

Those being, a significantly greater detection distance, attack range, projectile speed, and damage type (withering and blindness).

I'd like it to respond to player collision with a single high knockback attack.

I'd prefer if it was aggressive to everything except for other instances of itself.

And finally but optionally, I'd like it to share the behavior of zombies when attacked, specifically in that all others in render distance target the player, and more spawn nearby to join the attack.

Any help would be very, very appreciated!

Thank you all in advance!
