ImGui

ImGui is integrated into cerlib as a first-class component.

This means that it has tight integration and is automatically available to you.

ImGui is controlled via the CERLIB_ENABLE_IMGUI option, which is ON by default, so you don’t have to configure anything to access ImGui.

First, #include <imgui.h>.

Then just use Game::setImGuiFunc() to set the function that performs the ImGui rendering.

#include <imgui.h>

// ...

auto game = Game("My Game");

game.setImGuiFunc([&] {
    ImGui::Begin("My ImGui Window");
    ImGui::Text("Hello World!");

    if (ImGui::Button("Click here")) {
        logInfo("Button was clicked!");
    }

    ImGui::End();
});

while (game.tick()) {
    // ...
}

The function you pass to setImGuiFunc() is automatically called by cerlib at the right time, at the end of your game loop.
