I'm trying to use a UDT to manage all Player Sprite variables. I know that you can create a sprite like so:



However I am trying to use the UDT, Like this:



I get an error of "Sprite 0 does not exist at line 43 in root". What am I doing wrong?

I found that if I don't cast the ID variable, it works fine.

This code should work.

What's at line 43? This typically isn't the error you'd get when making a sprite but when you're trying to use one. Check for typos, I've often been caught out on them.

I've had no problems casting ID variables as integers. It sounds like there's a syntax error in there somewhere to me as Hodgey suggested.

Can you post the first 43 preferably 50 lines (sometimes the IDE can't add up too well )?

This line is the problem.

Your trying to create a sprite with no image assigned. You need to pass a valid image number into the CreateSprite() function.

No you don't. Using zero creates a blank / white sprite.

I'd Imagine so, I learned you could do it from the newsletter!

It's quite a handy feature actually. I use blank sprites set the colour and alpha to black / semi-transparent and stick it behind a pop-up menu such as "Quit Game? Yes / No" and it is a cheap way to fade the background out (for example).

They are also great for making lines...

Spooky, that's exactly how I use it! I'm just about to add colour values to my text/message system so I can overlay with different colours.
