First the code:



When clicking on the sprite I get an error message telling me the sprite does not exist.

I have tried making both the image and sprite global but that does not work.

Here this will work.


if you don't set the variable sprite to 0 the second loop through will throw an error

The variables will have to be global if they are to work across multiple functions.

With AppGameKit I've learnt that it is always a good idea to check if a sprite exists (using the GetSpriteExists()) before using it in another condition.

I would agree but only under certain circumstances. I wouldn't use it too often!

I like to know when a sprite exists and use arrays or other means to make sure that when I'm doing something to a sprite it exists for definite!

It is time for a great debate baxslash! ....ok you win.

You are correct baxslash, I meant to say that in the nature of his functions it's a good idea...but just didn't say it.

Ironically, I had my array algorithms in mind when typing that response.

After experimentation I have discovered the best way to do this is to use an array. Since arrays are global I can add the sprites to an array at the beginning then simply scroll through the array doing needed actions to the sprites later.
