The Mysterious Case of the Unneccessary Brackets

[Lone-Wolf]

The script editor is asking for those unneccessary brackets that when I put them in it demands they be removed.

Whenever I try to run this line:

_a setvelocity ((velocity _a select 0 + ((2 * (cos (90-(_dir))))))),((velocity _a select 1 + ((2 * (sin (90-(_dir))))))),((velocity _a select 2)-1)];

(BTW, its all on the one line rly)

The editor says: "Error: Type Any, Expected Number" (referring to the middle section of [*,*,*])
and it also says: "Error: Missing )" seemingly expecting one after the line's end.

I've stripped it apart and tried each piece seperately and found that sometimes a piece works on it's own but not in the line as a whole or that when I run the script it spontaneously works fine and then when I run it again w/o changing anything it has a million errors!

In a nutshell:

 

Help?

seems alright

well just introduce local vars

_var1 = 90-(_dir)
_var2 = cos(_var1)

etc

Try

Code: [Select]

_a setvelocity [(velocity _a select 0) + (2 * cos (90-_dir)), (velocity _a select 1) + (2 * sin(90-_dir)), (velocity _a select 2) -1];
Was missing opening [ and had far too many unnecessary brackets. Also, it may not make any difference but I generally have sin and cos the other way around, ie sin for x and cos for y.

The latter worked fine so thanks a bunch.
