Hey All. :)

Version: 08-01-2015 nightly linux debug

As permanently checking changelog. And people in irc says "every line is evaluated"

Can somebody confirm this ridiculous behaviour:

Code:

[function f_learn]

local.x 1

local.y 10

local.x += 1

local.y -= 5

sysmessage "<dlocal.x> <dlocal.y>" // Returns: "2 5"

local.x 1

local.y 10

local.x+=1

local.y-=5

sysmessage "<dlocal.x> <dlocal.y>" // Returns "1 10"

local.x 1

local.y 10

sysmessage <dlocal.x>+<dlocal.y> // Returns "1+10"

local.x 1

local.y 10

sysmessage <dlocal.x> + <dlocal.y> // Returns "1 + 10"

Just paste it in your sphere and run .f_learn

Looks like trusting and NOT using "eval" in expressions is totally biggest fault for scripting :D

IMHO:
Example #4 shouldn't work because there are spaces...
Example #3 SHOULD work because there are NO spaces and NO quotes
But most killing thing... #2 & #1... now I'm totally unsure can i really use "newgold -= 5000" or "newgold-=5000"

Update:

Code:

[function f_learn]

gold 1000

sysmessage "1000 -> <gold>" // 1000 -> 1000 (works)

gold += 1000

sysmessage "2000 -> <gold>" // 2000 -> 2000 (works)

gold+=1000

sysmessage "3000 -> <gold>" // 3000 -> 1000 (broken)

gold -= 1000

sysmessage "2000 -> <gold>" // 2000 -> 0 (works)

gold-=1000

sysmessage "1000 -> <gold>" // 1000 -> 1000 (broken)

local.x+=XXXX without space to equal symbol ( = ) i think sphere read it like "YYYY=XXXX" means YYYY for 'local.x+' and XXXX is value, so in your example can u check (for example #2)

Code:

local.x 1

local.y 10

local.x+=1

local.y-=5

sysmessage "<dlocal.x> <dlocal.y> <dlocal.x+> <dlocal.y->" //Now it should Returns "1 10 1 5"

and sysmessage command (#3,#4) i think it want string value so actually you have to do it like

Code:

local.x 1

local.y 10

local.temp = <dlocal.x>+<dlocal.y>

sysmessage <dlocal.temp>

or as you discuss u have to use "eval" experession before sysmessage command reads for string. like; <eval <dlocal.x>+<dlocal.y>>

Just use eval everywhere..
100% sure it will work

That's what I really started doing Big Grin

I'm not sure if I did understand this but this is my contribution:

- You should use local.bla += x and NOT local.bla+=x
- Values are stored in hex, so it doesnt matter if you use local.bla = <eval 8+2> and local.ble = <dlocal.bla> because they will be stored as '0a' anyways, so using evals to storage is a waste of cpu.
- Numerical strings SHOULD be eval'ed to output them

Xun, My question was related only to #1
but having stuff like "attr=010" and then you see "color += 01", slightly messing, isn't?
