Image not showing

why is my enemy image not showing?

//characters

if i delete it it goes way too fastl.

That’s fine! We can fix that properly!

Instead of using delay(), check the value of millis() and only update things if it’s changed by over 100.

int last_time = 0;

void setup(){
  // ...
}

void draw(){
  if( millis() > last_time ){
    last_time = millis() + 100;
    // Do other things that should happen only once every 100 milliseconds.
  }
}

why is this better than using delay()?

The delay function is pausing everything from happening. It just wait for the desired time to pass and then resume onto the next line of your program.

It is usually bad practice because you are “loosing” that time.

Using millis() as @TfGuy44 suggested, allow your program to keep running while running the desired part of your code only every 100 milliseconds. But if you need another part of your code to do something else in the meanwhile, nothing is preventing it this time.
