Variable assignment issue...

I mustn't understand something about the language, because I have no idea why this isn't working. That, or I'm having a bad day ;)

This doesn't work...

FinalPosX = StartPosX:+OffsetX

(error is: Expecting expression but encountered add sign)

This does, but seems to return the wrong thing...

FinalPosY = (StartPosY = StartPosY + OffsetY)

(I get the same error as above without the brackets)

Everything is Local, and Int. Have I missed something in the syntax, or do I need to post more code? The rest is very, very basic.

Both things are just syntactially wrong!

BM only allows you assignement per expression! But in both cases yo have 2 assignements!

Either yo have = or :+!

-> StartPosX :+ OffsetX
FinalPosX = StartPosX


I would have bet you already made this error once last week and got that explained

Thanks Dreamora, but what's with the whole...

?

No, I didn't. I'm just new to things like :+, and didn't realise you can't have an expression sorted and then assigned to a variable in one shot. I blame the manual which doesn't explain this kind of thing.

beside C no compiled language allows chain assignements unless I missed that so in the end the exception needs to mention its difference to the norm ... not the normally behaving one

Especially I can not remember that it is mentioned that this kind of assignement is allowed.

You can use:

A = A + 1

or

A:+1

Both do the same job.

If you want to do

A = B + C

Then that's pretty much the only way of doing it.
