Usage of AEGP_EffectCallGeneric() / PF_Cmd_COMPLETELY_GENERAL

[Justin T - Hyper Brew]

Trying to trigger an effect function from outside the effect. I apply both effects to a layer, and then trigger the message, but it's not recieved on the other end.

I believe I'm able to send AEGP_EffectCallGeneric() correctly by targeting the right layer (following the ProjDumper / Shifter examples), but I'm not able to trigger the other effect with PF_Cmd_COMPLETELY_GENERAL.

Am I missing a step here? Thanks!

Effect A (to send command):

[.........]

AEGP_SuiteHandler suites(in_data->pica_basicP);

A_long          num_effectsL, num_paramsL;

A_char          effect_nameAC[AEGP_MAX_ITEM_NAME_SIZE] = { '\0' };

AEGP_LayerH         layerH = NULL;

AEGP_CompH          compH = NULL;

AEGP_EffectRefH     effectH = NULL;

AEGP_ItemH          comp_itemH = NULL,

                    active_itemH = NULL;

AEGP_CompH parent_compH;

AEGP_LayerIDVal id;

AEGP_ItemType       item_type = AEGP_ItemType_NONE;

ERR(suites.ItemSuite8()->AEGP_GetActiveItem(&active_itemH));

if (active_itemH) {

    ERR(suites.ItemSuite8()->AEGP_GetItemType(active_itemH, &item_type));

}

if (!err) {

    if (AEGP_ItemType_COMP == item_type) {

        A_long layer_indexL = 0;

        FILE                *out;

        AEGP_LayerH layerH = NULL;

        AEGP_CompH compH = NULL;

        ERR(suites.CompSuite4()->AEGP_GetCompFromItem(active_itemH, &compH));

        ERR(suites.LayerSuite5()->AEGP_GetCompLayerByIndex(compH, layer_indexL, &layerH));

        //AEGP_GetLayerFromLayerID()

        ERR(suites.EffectSuite2()->AEGP_GetLayerNumEffects(layerH, &num_effectsL));

        for (A_long jL = 0; !err && jL < num_effectsL; jL++) {

            ERR(suites.EffectSuite2()->AEGP_GetLayerEffectByIndex(S_my_id, layerH, jL, &effectH));

            if (!err && effectH) {

                AEGP_InstalledEffectKey key;

                ERR(suites.EffectSuite2()->AEGP_GetInstalledKeyFromLayerEffect(effectH, &key));

                ERR(suites.EffectSuite2()->AEGP_GetEffectName(key, effect_nameAC));

                if (!strcmp(effect_nameAC, "Effect B")) {

                    A_Time                  fake_timeT = { 0, 100 };

                    // Message Sending Correctly

                    err = suites.EffectSuite2()->AEGP_EffectCallGeneric(S_my_id, effectH,

                                                            &fake_timeT, (void*)"Message");

                }

            }

        }

    }

}

Effect B (to receive command):

[.........]

static PF_Err

RespondtoAEGP (    

    PF_InData       *in_data,

    PF_OutData      *out_data,

    PF_ParamDef     *params[],

    PF_LayerDef     *output,

    void*           extraP)

{

    PF_Err          err = PF_Err_NONE; 

    AEGP_SuiteHandler suites(in_data->pica_basicP);

    suites.ANSICallbacksSuite1()->sprintf(  out_data->return_msg,

                                            "%s",  

                                            reinterpret_cast<A_char*>(extraP));

    PF_STRCPY(  out_data->return_msg,

            STR(1234));

            out_data->out_flags |= PF_OutFlag_DISPLAY_ERROR_MESSAGE;

    return err;

}

[.........]

PF_Err

EffectMain(

    PF_Cmd cmd,

    PF_InData *in_data,

    PF_OutData *out_data,

    PF_ParamDef *params[],

    PF_LayerDef *output,

    void *extra)

{

    PF_Err err = PF_Err_NONE;

    try

    {

        switch (cmd)

        {

        case PF_Cmd_COMPLETELY_GENERAL:

            // This is not getting triggered

            err = RespondtoAEGP(in_data,

                out_data,

                params,

                output,

                extra);

            break;

there's a strange limitation with EffectCallGeneric. you can't call one

instance from another instance of the same effect.

for example, you can't call a blur from a blur. you can call a blur from a

levels.

is that your use case?

Thanks, I did see that mentioned in another post, but no that's not my use case. I'm sending the message from one effect to an entirely different effect.

Once I get this method working I want to call it from ExtendScript with ExternalObject as a DLL, but for now, I'm just trying to get it to work correctly in C++ space if that makes sense.

Think I'm just missing some step. Do you have to register PF_Cmd_COMPLETELY_GENERAL somehow before using it or should it work as long as it's listening for that option in EffectMain()?

[shachar carmi]

no, you don't need to register in any way, but let's check some silly

little detail?

does your plug-ins entry point respond to this selector? not all SDK

samples have that command defined in their call switch in the entry point

function...

Yes, I have the selector as an option on the switch in EffectMain() of Effect B ( see below ), but even when I set a break point at the EffectMain() switch, it isn't getting hit from the AEGP_EffectCallGeneric() from the other effect. However, when I debug Effect A, it appears that it's identifying Effect B, setting the reference, and running the call correctly...

@justintaylor Did you manage to fix this issue?
