Something I need to understand

[Starquizer]

When I tried to read the AI files of the campaigns, the first thing I found is "SetReplacements", what is the meaning of this function what does it do.

Also, there are many functions that I don't understand what they do, not what they take and what they return or how the functions are written. And I haven't found a program or a site that describes the purpose of the function. Thanks to any help in advance.

Those are common.ai functions. I belive JassCraft lets you browse through them.

Indeed but what is the effect of this function in the game, by adding this function how the computer will behave. I understand how to browse it but what does it do ?

SetReplacements
SetReplacementCount

I do not understand their effect in the game.

What do the following function do (NOTE: I asked what they do not how to use them):

AddAreaDamagerForUnit_Child
AddCaster
AddIndicator
CasterRecycleTimed

What is the difference between
"AddAreaDamagerForUnit_Child" and "AddAreaDamagerForUnit" ?

And what is the widget ?
