I believe this is your problem
Origin[2]+= 50
->
Origin[2]+= 50.0
Origins are floats and you are incrementing them with an integer so it counts as 0
As for changing the color, nothing comes to my mind right now but I believe it’s possible.
As for your setting health, I believe you should give your entity a size so it gets a hitbox
Code:
new Float:maxs[3] = {16.0,16.0,36.0}
new Float:mins[3] = {-16.0,-16.0,-36.0}
entity_set_size(susanoo,mins,maxs)
There should be a fakemeta method if you prefer so you can try and figure it out
