Enemy position selected from several possibilities

Hello and thanks for reading this message.

I come with a new question that probably has been answered.

I have several enemies on the stage, each one of them out of a hole. I wish every X time an enemy out of one of those random holes.

How I can make enemies appear in one of those random positions?.

Logically each enemy / hole, have defined X and Y coordinates, and I know their values??. But I do not know how to make an enemy appears on screen using those coordinates as a reference. I suppose I should store these somewhere.

Here, an illustrative image of a similar game that I want to do:

Thanks and I hope you can help me, because I do not know how to do this.

Hi

an easy way to create something like the image above would be to have 9 enemies all set to invisible then choose a random number between 1 and 9 and make that enemy visible.

use the pick random instance and have a sprite for each enemy spawn point

and spawn the enemy from random instance of the spawn point

Thank you for your suggestions, I'll have to try if I can make them happen.

If I have any problems I will write, but I hate to bother you.

A greeting ;)
