[solved] Using z pos in a move?

[GentleSlayer]

Alright I just found out that the reason the spawner was moving indefinitely upward was because of a dvy: -1 in the opoint of the attack.

Thanks to Nyamaiku I could make spawn balls in a way more proper way than totally randomly XD
Then came the solution of YinYin which was to use hit_j to make the spawner move in the z-axis, and that is what I was looking for apart that I didn't know how I could make the balls spawn properly.

With all the explanations I got on hit_j I couldn't understand what was wrong with a certain invisible boundary until I put state 3000 on a new made ball a few minutes ago (I was using 3005). I thought maybe seeing a shadow would help me figure it out, and lol I just noticed that hit_j was working perfectly well and because of having no shadow and a high y pos opointing the spawning ball seemed to stop in the middle of the screen.

Now I can make a ball not too high from the ground move in the z-axis and spawn a multiple other balls in a clean way!

I'd like to thank you again guys for your incredible patience and kindness
