gd-imgui-cocos

imgui in gd using only cocos! ~~no hooks or anything~~ for geode

setup

link to it like any other cmake library, you can also use cpm which comes with geode

CPMAddPackage("gh:matcool/gd-imgui-cocos#commithash") # specify a commit!

target_link_libraries(${PROJECT_NAME} imgui-cocos)

You may specify what version of imgui you want to use by setting IMGUI_VERSION before including the library:

set(IMGUI_VERSION "v1.70")
CPMAddPackage("gh:matcool/gd-imgui-cocos#...")

Or even get imgui yourself, and setting the HAS_IMGUI option:

add_subdirectory(my-epic-imgui)

set(HAS_IMGUI ON)
CPMAddPackage("gh:matcool/gd-imgui-cocos#...")

usage

Make sure you call the setup method! Even if you don't need the callback you can use the overload with no args.

#include <imgui-cocos.hpp>

$on_mod(Loaded) {
    ImGuiCocos::get().setup([] {
        // this runs after imgui has been setup,
        // its a callback as imgui will be re initialized when toggling fullscreen,
        // so use this to setup any themes and or fonts!
    }).draw([] {
        ImGui::Begin("My awesome window");

        ImGui::Button("Awesome button");
        
        ImGui::End();
    });
}

This code will create a floating window that will persist throughout scenes, and should always be on top of everything

random

Heres how you can add your own fonts from mod resources, because i always forget.
Make sure that in your mod.json the ttf is a file, instead of a font! you don't want it as a gd font, you want the actual ttf file

ImGuiCocos::get().setup([] {
    // you should do this in setup! ok thx
    auto* font = ImGui::GetIO().Fonts->AddFontFromFileTTF((Mod::get()->getResourcesDir() / "whatever.ttf").string().c_str(), 16.0f);
    // do something with the font.. like io.FontDefault or something
})//.draw(... etc
