Hi all.
I'm really new to lua/tolua and I need some clarification about how
exactly the integration must be made.
In fact I want to see how usefull is tolua to integrate scripting
functionality to given classes. For that, I've build a really basic
classe in file Object.h/Object.cpp and from the header file I've create
a clean version name Object.pkg.
After this I know that I must build the binded file via :
tolua++ -o Object_Bind.cpp Object.pkg
or
tolua++ -o Object_Bind.cpp -H Object_Bind.h Object.pkg
The goal of this is to allow me to build the following script :
obj1 = Object:new()
obj1:SetName("Name1")
obj2 = Object:new("Name2")
obj1:Display()
obj2:Display()
obj1:delete()
obj2:delete()
The big problem now is that I don't know what I need to include in my
main.cpp file. What I've made build correctly but as soon as I run it it
crash.
I'll really appreciate all the possible help. Any pointer to tolua
exemple are really welcome.
I've found Doris application but it's a little bit to complex to begin
for study tolua.
Really thanks.
