My answers won't be too specific, so I recommend you refer to the Command Prompt page. If you're not comfortable with using commands, check TingThing's tutorial. It may be a good idea to watch the entire playlist in general, it's a nice starting point: you may even learn some new things
https://theplatformbuilder.com/command-prompt/1. You can change coin sprites from the Items 2 sprite sheet, alternatively upload your graphic as a "Sprite" and replace default coins with custom items. This has other perks as well.
2. The easiest solution would be to change currencies from coins to stars. If this has to be money, you can add a conditional like this:
if money=100
{
money=0
//add whatever you want to happen
}Best used with a custom item, as they have command prompts that can check for this only when they're collected. Adding this to a Looping command prompt would work fine, if not a bit wasteful. Looping prompts essentially repeat a set of commands every few frames.. so don't get too carried away or your game might get choppy
3. Yes, you can change most of the HUD with commands. I don't remember if anyone made a good tutorial/presentation... it would be useful because it's pretty clunky and unintuitive. I could guide you through that process if you want to deal with that.
4. Change scrolling settings from Loose to Fixed (I believe that's what they're called). The screen will stay fixed vertically.
5. What enemy are you using? Is it one of the default ones or is it custom?
6. Automatic isn't the default setting. I'm not sure what you mean by this, did you change th setting somewhere or do you want to limit the amount of bullets that can be on screen?
