Well im trying to learn BASIC again. Havent used it in awhile and pretty much forgot it all. Doing this tutorial, and im stuck. Here's my code:



in line 2
Quote: "if Button(240,200,"New Game")=1 then goto New_Game"

When i click compile and run the line is highlighted and the code doesnt continue. Im sure it means its an error, but i have no clue whats wrong with it.

Thanks in advance.

you don't need those "endif" statements. if-then doesn't require an endif. I'm not sure if it's a runtime or a compile time error by what you've said, but i'm pretty sure it's compile time. Basically, the if/then thing is already closed as far as the compiler is concerned, so you're trying to end another if.

The endifs and your function isn't returning a value. Your function needs to end like: "ENDFUNCTION pressed"

At the risk of being rude, I wouldn't trust any tutorial which uses Goto without explaining why it shouldn't be used - as it shows a lack of programming experience.

And, assuming that the Endifs aren't an error on your part, I'd scrub that source of tutorials off your 'must read' list.

I do firmly believe that there are far too many very poorly written and therefore damaging so-called tutorials out there.

Obviously I have to declare an interest as I put a lot of time and effort into writing them myself so it's annoying when people like you are being led astray by bad tutorials.

Don't get me wrong, there are lots of excellent tutorials out there written by lots of people.

It's just the few bad ones like the one you have encountered - which is wrong on so many levels - that give all tutorial writers a bad name.

is looking for a return value from the function. If you just ENDFUNCTION, nothing is returned. "Pressed" is the variable that you are changing inside the function:



So you would want to return that variable when the function ends "ENDFUNCTION Pressed"




If instead you put:


You would have to change the code where you call the function to:


I hope my explanation isn't too confusing.

Hypothetically:
If the code was..


Then the code would have..

Yes - that's correct... but only if you want to return that value (Clicked) from the function.

If you didn't need it, you wouldn't return it.

Then they can't be all that good as all this is covered in the one on Functions!
