• XLua » Actions » Variables

This group of actions lets you directly set the values of any globally-defined variables in the Lua state. All variables are global unless they are prefixed with the "local" keyword, or if they are part of a module.

XLua supports the complete Lua syntax for variable names, including accessing tables and arrays. Some examples of valid names are:

• apple
• fruit.grapes
• mylist[1]
• colors['blue']
• position[20][30]
• complex.tables['rock'].my['socks']

Be aware of the difference between numeric and string indices. [1] and ['1'] are both valid, but different indices. A name such as mylist.1 is an invalid Lua name, but is valid in XLua and is the same as mylist['1'].

Currently there is the limitation that ., [], ', and " characters cannot be used in string indices.
