imgui module for the LÖVE game engine including lua bindings based on this project. The main difference is that now by default in this version the return values ordering is reverted. For instance to retrieve the value from a slider, you need to do:
floatValue, status = imgui.SliderFloat("SliderFloat", floatValue, 0.0, 1.0);Or if you're not interested to know if the field was modified, just:
floatValue = imgui.SliderFloat("SliderFloat", floatValue, 0.0, 1.0);To reverse this behavior and receive back the return values from a function first before the modified fields, just call at the beginning of your application:
imgui.SetReturnValueLast(false)Another notable difference is that enum values are handled using strings (and array of strings) instead of numerical values, for instance to create a window:
imgui.Begin("Test Window", true, { "ImGuiWindowFlags_AlwaysAutoResize", "ImGuiWindowFlags_NoTitleBar" });Or for a single flag:
imgui.Begin("Test Window", true, "ImGuiWindowFlags_AlwaysAutoResize");It uses imgui 1.75 (as a submodule) and is based on LÖVE 11.1.
Just build the project, and copy the generated dynamic module next to your love executable or into the LÖVE application data folder (for instance "C:/Users//AppData/Roaming/LOVE" on Windows or ~/.local/shared/love on Linux).
Pre-built binaries for Windows and Mas OSX are provided in the releases page.
Simple integration:
local imgui = require "imgui"
local showTestWindow = false
local showAnotherWindow = false
local floatValue = 0;
local sliderFloat = { 0.1, 0.5 }
local clearColor = { 0.2, 0.2, 0.2 }
local comboSelection = 1
local textValue = "text"
