C# and C++ wrappers to develop Gamemaker DLL extensions easily
Don't forget to define RegisterCallbacks(int, int, int, int) in your extension's functions in Gamemaker Studio.
Just drop .cs file into project, then import namespace using Gamemaker.Internal;
Map can be edited with [] notation or via AddKeyValuePair() method. Brackets allow any value type (incl. other DsMaps), floating and integral (up to 32-bit) types will be stored as doubles, booleans will turn into 0/1, null will be empty string, other DsMaps will be stored as their ID number (double), everything else, the ToString() method will be called on, including 64-bit integers. So for complex object types it's handy to define ToString() method which results with a JSON representation which can be then parsed back in Gamemaker if needed.
DsMap.Dispatch has several overloads, so you can not only define callback type but also result type (default is _type_ key) as string or number, which can be useful for determining what kind of information is returned.
In the end use DLLExport to generate export signatures.
DsMap result = new DsMap((int)EAsyncSteamType.leaderboardDownload);
result["success"] = true;
DsMap entries = new DsMap();
result["entries"] = entries;
result.Dispatch(EGmsEventType.EVENT_ASYNC_STEAM);Add gamemaker.cpp and gamemaker.h to your project, then #include "gamemaker.h" in your project and using namespace gamemaker;
It's pretty similar to C# version but being a little outdated, so there's some inconsistency, so result types are defined in constructor and there're no brackets editing, only set() method
ds_map report("_result_", result_status);
report.set("value", (double)10);
bool dispatch_res = report.dispatch(gml_event_type::social);
