This is an unsafe mod that allows other mods to use ImGui to create user interfaces without enabling unsafe mode themselves! I hope people will consider using this when the find the standard Noita GUI API too limiting.
Here's a small list of functions that show what ImGui is capable of: InputText TableNextColumn SliderFloat IsMouseDoubleClicked IsKeyDown ColorPicker4 SetClipboardText.
Checkout the README for more info on how to use it: https://github.com/dextercd/Noita-Dear-ImGui#readme
Put the NoitaDearImGui folder in your Noita mods directory. You can also add NoitaDearImGuiExampleNative and NoitaDearImGuiExampleMod to enable the example mods.
Make sure NoitaDearImGui is always above any mod that uses ImGui in the mod load order.
