Help me please. I need to have this done today

Can you be more specific about what want to happen?

Two questions:

  1. Do you want to add a predetermined number of enemies? Or the ability to have a variable number of enemies?
  2. What is the deterrent to the enemies’ interaction? For example, when the enemies come within range or overlap something of consequence happens? Like the game stops or you lose points (if there is a scoring component)?
4

so the enemies don’t need to be a variable and if the player comes to close to them, the player loses a life. The enemies move left and right but stay around the same area.

5

I hope that makes sense

6

You mean there is a set number of enemies at the outset of the game?

7

yes that’s what I mean

8

Since it sounds like you want multiple enemies that all have the same appearance and functionality, have you studied OOP yet? Classes and objects?

9

no we haven’t done that

10

Ok, so basically to set up one enemy you can:

  1. set up a simple primitive shape as the enemy. In this case, an ellipse will work.
  2. use the dist() function to determine when one of your characters comes near the enemy
  3. use if-statement construct to outline the consequence when character nears or touches the enemy

Here is an excellent tutorial by Abe Pazos on how to use the dist() function:
