[Solved] IF-statement with custom script

[TheHook]

Is it possible? Most tutorial dealing with custom scripts only use them for "call functionName()"

Yes, it's possible, but you need to know JASS to properly use custom script.

Read the "Condition" chapter here: https://www.hiveworkshop.com/threads/jass-or-what-the-func.238298/

Thx, very useful. It is strange that none of "Custom script" tutorials explain IF-THEN_ELSE use...

 

[Dr Super Good]

They do not explain it because once you get to the stage you are using custom script for conditional statements you might as well switch entirely to writing JASS.

If statements are available in GUI without custom scripts.
Custom functions, Common.j functions, easier string concatenation and number calculations, etc are not. That is what you will see in those custom script tutorials. (Ofcourse next to JASS syntax, global variable usage and all the other stuff you need to know.)

There are, indeed, GUI-based IF-statements. The problem is, they cannot directly access local variables. There is a workaround, but it's bulky (reassigning local variable value to global). I just needed to quickly compare two locals I and J, if equal, set K to 1. Not enough to warrant rewriting trigger in jass, one line of custom code IF should be enough.

Hm, I still get "End of line expected" whenever I try to use IF-statement in custom script. Example:

Custom script: If i==j then set k=1 endif

Results in an "Expected end of line" error

Results in an "Expected end of line" error

That is because it is malformed JASS. Line separators matter in JASS.

Try...

• Custom script: if i==j then
• Custom script: set k=1
• Custom script: endif

Remember that GUI global variables are start with the "udg_" prefix.

Thanks! Works like a charm. Now that newfound power will reduce hashtable load.
