Okay, I'm getting stuck again..
General enemy AI ✓
Missing things: 1. Since enemy spawn is randomized, running into an enemy out of nowhere would surely be unpleasant. I had this idea of making an animation that starts with the sperm cells initially popping out of the depths from a shadow (that can't harm the player, but after a brief moment the sperm cells are able to hurt the player), unfortunately I can't figure out the event coding.
Score bar ✓ (I called it Experience)
Dash mechanics ✓
Missing things: 1. How do I make the dash unavailable for a determined number of seconds after being used (trigger = hold right click)
2. Possibly a dash bar to show the cooldown?
Help items X
1. I don't know how to implement the items in such a way that it spawns precisely on top of the concrete pool flooring.
2. Since the player can't pass through the solid borders, I was thinking of getting the items by facing the items directly and clicking Left click. To utilize the items, press Left click again.
Items are in the form of health recovery and temporary shield (that can be destroyed by enemy collision).
Phew, that's a lot. If you do decide to pay attention to this very long post, I can only give you my thanks (or a donation? I can buy you a cup of coffee). There's no rush to complete this project so you don't need to answer everything at once. Once more, thank you very much!
Edit: I bought you coffee, thanks :))
