Wrapper for opcodes is missing

[goodidea82]

Some earlier version had a wrapper (SCMWrapper) for opcodes (developed by fastman92), but now the API is missing:
https://github.com/DK22Pac/plugin-sdk/blob/master/src/sdk/plugin/script/wrapper.h
This API is important for because I already have a lot of custom code that depend on it.

It's possible to "call" an opcode in this way:

#include "extensions\ScriptCommands.h"
using namespace plugin::test;
// ...
ScriptCommand<PRINT_NOW>("FEC_INC", 150, 1);

#include "plugin_III.h"
#include "extensions\ScriptCommands.h"

using namespace plugin;
using namespace plugin::test;

class Gta3ScriptCommandsTest {
public:
    Gta3ScriptCommandsTest() {
        Events::processScriptsEvent += [] {

            int PlayerChar, PlayerCar;
            float CoordX, CoordY, CoordZ;

            if (ScriptCommand<IS_PLAYER_PLAYING>(0))
            {
                ScriptCommand<GET_PLAYER_CHAR>(0, &PlayerChar);
                if (ScriptCommand<IS_CHAR_IN_ANY_CAR>(PlayerChar))
                {
                    ScriptCommand<STORE_CAR_CHAR_IS_IN_NO_SAVE>(PlayerChar, &PlayerCar);
                    ScriptCommand<GET_CAR_COORDINATES>(PlayerCar, &CoordX, &CoordY, &CoordZ);
                    ScriptCommand<DRAW_SHADOW>(3, CoordX, CoordY, CoordZ, 0.0f, 3.0f, 150, 255, 0, 0);
                    ScriptCommand<PRINT_NOW>("FEC_INC", 150, 1);
                }
            }
        };
    }
} test;

Thanks for the quick reply.
I have a special use case where wrapper functions are automatically generated for opcodes.

Can I use hex-numbers instead of opcode names? E.g.
ScriptCommand< 0x00AA >(PlayerCar, &CoordX, &CoordY, &CoordZ);

Do I need the "Events::processScriptsEvent += [] {...}" to call an opcode and what does it mean?

I want the called opcode have the same effect on the current thread as a normal opcode would have. How do I pass the thread-pointer to the ScriptCommand? (or obtain a thread pointer if it has its own thread) In my code I have a function "copyThreadAttrToWrapper" that translates the state from the current thread to the fastman's SCMwrapper's thread and "copyWrapperToThread" to translate it back.

Here is an example of what I mean:

void op00A0(DWORD actHandle1, float& varX2, float& varY3, float& varZ4){
SCMwrapper.PushInt(actHandle1, true);
SCMwrapper.PushFloat(varX2, true);
SCMwrapper.PushFloat(varY3, true);
SCMwrapper.PushFloat(varZ4, true);
copyThreadAttrToWrapper(curThread, SCMwrapper, (curThread->notFlag? 0x80A0: 0x00A0));
cmdResult = SCMwrapper.CallCommand(curThread->notFlag? 0x80A0: 0x00A0);
copyWrapperToThread(SCMwrapper, curThread);
SCMwrapper.SaveReturnedValues(retVal);
varX2 = varX(retVal.returnedValues[1].Float);
varY3 = varY(retVal.returnedValues[2].Float);
varZ4 = varZ(retVal.returnedValues[3].Float);
}

The easiest for me would be if fastman's SCMwrapper API would be added back.

Yes.

It's recommended to 'call' opcodes when scripts are 'processed' (i.e. executed). That's why processScriptsEvent event is used in this example.

How do I pass the thread-pointer to the ScriptCommand?

Not possible yet.
