Sorry I dont know the proper way to describe this, but I have for example a call to a function, and it is long, to long for one line, so after the comma separating the function parameters I drop the rest down to the following line, to aid in readability.

Doing this in most other languages or IDE's is no problem, but in the AGKv2 IDE the code will not compile if you break up a long function call over two lines.

Ill add an image to show you the function call that wont compile because its split over two lines.

Is there a way to do this that I am missing?

Thanks

line breaks in AppGameKit basic indicate new lines for the compiler like you'd do with a semicolon in most languages.
You can't have line breaks in a single AppGameKit command like this.

Thanks Naphier,

The reason I was confused is I had been copying and pasting code from some website, not sure where, and they had seemed to be useing underscores__ which I had to keep removing

Thanks for the info

I think you want to store those joystick values in a variable anyway, you might end up having to limit the speed for example, as I don't think joystick values are normalized. Like, if you only want the sprite to move by 1 unit at a time... well what if the stick is right in the corner, and X and Y both give 1 - the sprite would actually be moving at more like 1.3 units, or you might want a deadzone, so maybe the last 25% of the joystick range gives a limited full speed. It might make sense to store these values now regardless.

I am the one who knocks...

Hi Van B

Thats good advice, ill keep that in mind.

I wasn't actually using the joystick code here tbh, its just left over code from a hacked apart example

Thanks though, I really do appreciate the input. I'm sure ill be using the joystick before long

In DBPro, you could use _ to continue on a new line, doesn't seem to work in AGK.

The problem is that in AppGameKit (like Visual Basic), a carriage return signifies a new line.

In C++, C#, or Java, you use a ;
So in these languages you can split the line as it ignores the carriage return.

Unfortunately, BASIC shows its age in actually requiring blocks defined by new lines, rather than by white space. In C it's the \ character that defines a continuation.

I'm pretty sure that if there was enough call for a method of continuing a line it could be easily written into the compiler. It's not a 'requirement' of BASIC (or some relic from a bygone age) that means this has to happen in AppGameKit

Personally I quite like using an end of line semi-colon in C# (as with many other languages) it simplifies the whole thing. Not sure we couldn't add something similar into AppGameKit too if there was call for it but when the language was in its infancy a lot of these sort of options were discussed with the community, not sure if this was one of them...?

I shall refrain from pointing out that in Pascal you can do this (apart from splitting a string in the middle) with no need for a continuation symbol.

Its only a small thing really, Its still been a pleasure to work with AppGameKit when I throw out some of my preconceptions coming from Java, and having no experience with procedural languages

I've spent the first couple days banging my head against the procedural programming style, but I've accepted it now and I'm trying to bring some pseudo Object Orientation to my game making with AppGameKit

@BatVink I must have been looking at DarkBasic code by the sounds of things then

Thanks for the input guys
