C++ (Cpp) UIElement::setAppearCondition Examples

Example #1

File: GameWinScene.cpp Project: gdxn96/swarm-wars

void GameWinScene::createUIElements()
{
	UIElement* element = new UIElement(UI_TYPE::BUTTON, GameConstants::WINDOW_CENTRE, Vector2D(50, 50), ">You Win!\nPress A to return to \n Main Menu<", "exit2");

	element->setAlpha(0);
	element->setAppear([element](float dt){ element->changeAlpha(510 * dt); });
	element->setAppearCondition([element](float dt)->bool{ return element->testAlpha(255, 255 * dt); });
	element->setDisappear([element](float dt){ element->changeAlpha(-510 * dt); });
	element->setDisappearCondition([element](float dt)->bool{ return element->testAlpha(0, -255 * dt); });
	element->setSize(150);
	m_menu.addElement(element);
}
