for me to use this variable is inconvenient

may use it like?

gyroscope

No, that won't work at all. Try (with example to add them):

game.Box (chosen from via the Editor, not typed) +self.1 + self.j

Also, a small tip, to make your attribute names with more information (actual words) because if you're project gets complex with lots of single letters, it'd be easy to get confused.

Hope that helps.

Edit: or if attributes are text, concatenate (join one after the other) as TSB wrote.

if i write "game.Box.37" then Invalid Expression
"game.Box..self.i..self.j" Empty
"game.Box...self.i..self.j" Invalid Expression
"game.Box..(self.i)..(self.j)" Empty
"game.Box...(self.i)..(self.j)" Invalid Expression

Why can not

Yarik

no... this not working
i think problem is not .. or +
if write game.Name or game.Box.37 then shows Invalid Expression

Hi Yarik, what type of attribute is game.Name? And what type of attribute is game.Box.37? Also calling an attribute, whatever type it is, with a fullstop is not good either, should be called Box37, and so shows up in the Editor as game.Box37.

Yarik

Name - text
Box.37 this is not name, name is 37,
Box is size for variable, like self.Position or self.Size

37,i,j - I tried it with Index and real

Still confused about game.Box.37; but for certain you can't mix text attributes with any number attributes in the Expression Editor unless the Expression Editor is accessed via a Display Text Behaviour.

So, as far as I can make out Name is a text attribute, 37 is a text attribute and Box is a variable attribute: integer, real or index.

Fo this example, lets say the following values are: Name = John; Box = 37;and we'll give i the value of 28; and j the value of 290.

So using the Expression Editor in a Display Text Behaviour, if you put, (as TSB said):
Name...Box...i...j you'll get:

John3728290

If you put Name..." "...Box..." "...i..." "...j you'll get:
John 37 28 290

Still confused what your actual values are but hope that's helped.

no
game attributes
real game.11 = 478
real game.27 = 996
real game.34 = 754

actor attribute
real self.i
real self.j
display text: game.(self.i)(self.j)

if i=1 j=1 then show 478
if i=2 j=7 then show 996
if i=3 j=4 then show 754

is similar to a static array

Right, OK! I'm getting there:

game.11 = 478
game.27 = 996
game.34 = 754
self.i
selfj

if i=1 j=1 then show 478
if i=2 j=7 then show 996
if i=3 j=4 then show 754

478, 996 and 754 need to be put into attributes, presumably either self.i or self.j?

Display Text: (self.i)..(self.j)

Say self.i becomes 478 and self.j becomes 996, then you'll get displayed:

478996

If you want 478 996 then put:

Display Text: (self.i).." "..(self.j)

Forget, I asked stupid
wanted to work with a static array
but I forgot that I can not enter the expression into the first slot "Chang Attribute "

but even so thank you very much
