variable for all script in the editor

[montagneyaya]

Is there a way for create a variable usable in all script in the editor ?

You can refer to a variable in another script entity without problems, prefixing it with the name of the entity followed by a dot ".".
If you can't write it (I haven't tested) you can put a couple of methods in that entity to wrap the variable (this is a good practice anyway and is the reason I didn't test the variable access really).

I'm not positive but I seemed to not be able to affect the variable from another script entity, only read it. So if I had
badLunchScript which contained:

Code: Select all

hotDogs = 4
applePie = 8

function eatSomeLunch()
  hotDogs = hotDogs - 1
  applePie = applePie - 1
end

Then I can have another script entity in the dungeon called goodDinnerScript which contains:

Code: Select all

peptoBismolSpoons = 0

function setSpoons()
  peptoBismolSpoons = badLunchScript.hotDogs
end

but the only way to change the variable hotDogs is to do it inside badLunchScript. So if I'm still in goodDinnerScript, I can write this:

Code: Select all

badLunchScript.eatSomeLunch()

I'm pretty sure you're right Komag as I remember reading that you can only modify a variable from the script entity it is in.

Should be pretty easy to set up a few function to do it though.

Code: Select all

my_variable = 0

function incrementMyVariable()
  my_variable = my_variable + 1
end

function decrementMyVariable()
  my_variable = my_variable -1
end

function setMyVariable(x)
  my_variable = x
end

then call something like:

Code: Select all

my_script.setMyVariable(5)

Ok thank you all for this info
It will be a great help

Yup! Coincidentally, using "getters" and "setters" like these is often regarded as a good programming practice anyway even if you would be working in an environment where you could directly modify pretty much any variable. This way you can, for example, expand and build additional logic into the getter and setter functions later on so that you could build a check that a variable stays within a certain range and so on.
