# ImGuiEXT of adxe
|
|
Sync from https://github.com/Xrysnow/cocos2d-x-imgui and do a little changes
|
|
|
|
## Improvements
|
|
* Simplify API, use add/remove renderLoop present ImGui GUI widgets
|
|
* Optimize call pipeline flow, support add/remove Node to Scene at ImGui render loop without container iterator damage
|
|
* Calculate deltaTime at ```ImGui_ImplCocos2dx_NewFrame``` to avoid error when ```cc.Director``` paused
|
|
* Refine ```Init/Shutdown```, Restore all callbacks for glfw to solve recreate ```ImGuiEXT``` instance support
|
|
* Use ```FOURCC``` for key of ImGui render loop
|
|
* Add dpi scale support, use ```ImGuiEXT::getInstance()->scaleAllByDPI(1.0);```
|
|
* Easy font manager, stable API ```addFont,removeFont,clearFonts``` to manage ImGui fonts, with ImGui API, very hard to do correctly.
|

|
## How to use
|
|
```cpp
|
|
#include "ImGuiEXT/CCImGuiEXT.h"
|
|
USING_NS_CC;
|
|
USING_NS_CC_EXT;
|
|
|
|
class GameScene : public Scene {
|
|
public:
|
|
void onEnter() override
|
|
{
|
|
Scene::onEnter();
|
|
ImGuiEXT::getInstance()->addRenderLoop("#im01", CC_CALLBACK_0(GameScene::onImGuiDraw, this), this);
|
|
}
|
|
void onExit() override
|
|
{
|
|
Scene::onExit();
|
|
ImGuiEXT::getInstance()->removeRenderLoop("#im01");
|
|
}
|
|
void onImGuiDraw()
|
|
{
|
|
ImGui::Begin("window");
|
|
ImGui::Text("FPS=%.1f", 1.f / ImGui::GetIO().DeltaTime);
|
|
ImGui::End();
|
|
}
|
|
}
|
