Part of the power of a scripting language like Lua, is that scripts can be loaded and re-loaded at run-time. This means you can test your game logic without having to re-compile your Objective-C++ code. In this recipe, we will load a remote script from a local web server.
Execute the following code:
#import "mcLua.hpp"
#import "Reachability.h"
@interface Ch7_DynamicScriptLoading : Recipe
{
class mcLuaManager * lua_;
}
@end
//Callback pointer
Ch7_DynamicScriptLoading *dslRecipe = nil;
//Static append message C function
static int dslAppendMessage(lua_State * l)
{
//Pass lua string into append message method
[dslRecipe appendMessage:[NSString stringWithUTF8String:lua_tostring(l,1)]];
return 0;
}
@implementation Ch7_DynamicScriptLoading
-(CCLayer*) runRecipe {
//Superclass initialization
[super runRecipe];
//Set callback pointer
...
