Replacing engine.controls.setButtonReleaseCallback in version 2.16.1

[karim.salama]

Hi all,

We're currently upgrading our codebase to be able to use the latest version of the Unigine SDK (2.16.1). And I've just realized that the Unigine::Controls::setButtonReleaseCallback function in no longer part of the Unigine SDK.

In C++, I could Unigine::Input::addCallback(Unigine::Input::CALLBACK_MOUSE_UP, Unigine::MakeCallback(...));. But in my case, this is implemented in UnigineScript, and it turns out that the addCallback function is not available in UnigineScript. Is there any workaround that adds an immediate callback upon a mouse event in UnigineScript without making an event filter function?

We are totally aware that the UnigineScript language is kind of deprecated and we aim to port all our existing scripts into C++, but first, we must port our current build to the latest version of the Unigine SDK.

Thanks in advance,

Karim

Hello,

The callback setup functions are still available in the script. Here is an example that works in version 2.16.1:

int on_button_press(int button)
{
	log.message("press: %d\n", button);
	return 0;
}

int on_button_release(int button)
{
	log.message("release: %d\n", button);
	return 0;
}

int init()
{
	engine.controls.setButtonPressCallback(functionid(on_button_press));
	engine.controls.setButtonReleaseCallback(functionid(on_button_release));

	return 1;
}

Hi karpych11,

Thanks! I didn't know that this function still exists in the SDK.

If you search for "setButtonReleaseCallback" in the documentation, you won't get any results.

Yep, UnigineScript documentation is not updated anymore (as it was marked as deprecated), but methods may be still available.
