Problem with App::clearMouseButtonState

[simakov.artem]

Hi all!

We want to check if the left mouse button was pressed once and so we use App::get()->clearMouseButtonState(App::BUTTON_LEFT) but then left mouse button is refused to work.

It's a bug or we do smth wrong?

 

Unigine version 2.7.2.1.

Hi Artem,

Could you please provide a sample code that you are using? Also engine startup options and defines (if any) will be interesting to see.

Thanks!

silent, I have test this on default new project without plugins (after all attempt to force to work in main project). Just I have added Unigine::App::get()->clearMouseButtonState(Unigine::App::BUTTON_LEFT) into AppWorldLogic::update().

Hello Artem,

That's the common pattern of using that function:

if (Unigine::App::get()->getMouseButtonState(Unigine::App::BUTTON_LEFT))
{
    Unigine::Log::message("pressed\n");
    Unigine::App::get()->clearMouseButtonState(Unigine::App::BUTTON_LEFT);
}

clearMouseButtonState is used here to log a message for every mouse button press instead of every frame when mouse button is pressed. Could you please elaborate what behaviour did you expect?

andrey-kozlov, if I use your example into project (even empty) GUI (buttons, tabs, etc.) doesn't work. I think it's not normal behaviour.

That's because GUI listening mouse buttons too. You could use Controls which is used for game logic exclusively.

Unigine::ControlsPtr controls = Unigine::Game::get()->getPlayer()->getControls();

if (controls->getState(Unigine::Controls::STATE_FIRE))
{
    Unigine::Log::message("pressed\n");
    controls->clearState(Unigine::Controls::STATE_FIRE);
}

Also we currently working on new input system which allows to handle keypress once in a more friendly way.
