ImGui

Bindings for ImGui directly inside lua.

Not all ImGui methods or enums are available. If you're in need of a specific method, you can ask on our Discord and we will try to add support for it as soon as possible.

`ImGui.Begin(id)`

id - The id of the window

Begins a new ImGui Window with the given id.

Example:

function render()
	ImGui.Begin("mymenu")
        ImGui.Text("some text")
        ImGui.End()
end

engine.addEventListener("render", render)

`ImGui.Begin(id, windowFlags)`

id - The id of the window
windowFlags - The flags for the window

Begins a new ImGui Window with the given id and additional window flags. For a list of available windowflags, check here.

Example:

function render()
	ImGui.Begin("mymenu", ImGuiWindowFlags.NoTitleBar)
        ImGui.Text("some text")
        ImGui.End()
end

engine.addEventListener("render", render)

`ImGui.End()`

Ends a ImGui Window.

Example:

function render()
	ImGui.Begin("mymenu")
        ImGui.Text("some text")
        ImGui.End()
end

engine.addEventListener("render", render)

`ImGui.PushStyleColor(colorIndex, color)`

colorIndex - The color index as a ImGuiCol
color - The color as a Vec4

Pushes a style color identified by the colorIndex. For available indices check here. All following rendered elements targeted by the index will have this color applied to them.

For each time you push a style color, you WILL have to use ImGui.PopStyleColor after you're doing using the given color for elements.

Example:

function render()
        ImGui.PushStyleColor(ImGuiCol.WindowBg, Vec4:new(255, 0, 0, 255))
	ImGui.Begin("mymenu", ImGuiWindowFlags.NoTitleBar)
        ImGui.Text("some text")
        ImGui.End()
        ImGui.PopStyleColor()
end

engine.addEventListener("render", render)

`ImGui.PopStyleColor(count)`

count - How many style colors to pop of the color stack

Pops a number of style colors of the color stack.

Example:

function render()
        ImGui.PushStyleColor(ImGuiCol.WindowBg, Vec4:new(255, 0, 0, 255))
	ImGui.Begin("mymenu", ImGuiWindowFlags.NoTitleBar)
        ImGui.Text("some text")
        ImGui.End()
        ImGui.PopStyleColor()
end

engine.addEventListener("render", render)

`ImGui.PushStyleVarFloat(varIndex, floatValue)`

varIndex - The variable index as a ImGuiStyleVar
floatValue - The value to set the var to

Pushes a style var identified by the varIndex. For available indices check here. All following rendered elements targeted by the index will have this style variable applied to them.

For each time you push a style variable, you WILL have to use ImGui.PopStyleVar after you're doing using the given style variable for elements.

Example:

function render()
        ImGui.PushStyleVarFloat(ImGuiStyleVar.WindowRounding, 10.0)
	ImGui.Begin("mymenu", ImGuiWindowFlags.NoTitleBar)
        ImGui.Text("some text")
        ImGui.End()
        ImGui.PopStyleVar()
end

engine.addEventListener("render", render)

`ImGui.PushStyleVarVec2(varIndex, vec2Value)`

varIndex - The variable index as a ImGuiStyleVar
vec2Value - The Vec2 value to set the var to

Pushes a style var identified by the varIndex. For available indices check here. All following rendered elements targeted by the index will have this style variable applied to them.

For each time you push a style variable, you WILL have to use ImGui.PopStyleVar after you're doing using the given style variable for elements.

Example:

function render()
        ImGui.PushStyleVarVec2(ImGuiStyleVar.WindowPadding, Vec2:new(16, 16))
	ImGui.Begin("mymenu", ImGuiWindowFlags.NoTitleBar)
        ImGui.Text("some text")
        ImGui.End()
        ImGui.PopStyleVar()
end

engine.addEventListener("render", render)

`ImGui.PopStyleVar(count)`

count - How many style variables to pop of the style variable stack

Pops a number of style variable of the style variable stack.

Example:

function render()
        ImGui.PushStyleVarVec2(ImGuiStyleVar.WindowPadding, Vec2:new(16, 16))
	ImGui.Begin("mymenu", ImGuiWindowFlags.NoTitleBar)
        ImGui.Text("some text")
        ImGui.End()
        ImGui.PopStyleVar()
end

engine.addEventListener("render", render)

`ImGui.PushFont(name, size)`

name - The name of the font
size - The size in pixels of the font

Available Fonts:

Verdana
VerdanaBold
Impact
Beyblade
Dameron
RobotoMono-Light

Available Font sizes:

12, 14, 16, 18, 24, 32, 36, 48, 60

Pushes a font. All following elements containing text will have this font applied until it is popped with ImGui.PopFont

Make sure to use ImGui.PopFont after you're done using the font. For one PushFont you want one PopFont.

Example:

function render()
        ImGui.PushFont("VerdanaBold", 32)
	ImGui.Begin("mymenu", ImGuiWindowFlags.NoTitleBar)
        ImGui.Text("This is written in Verdana Bold.")
        ImGui.End()
        ImGui.PopFont()
end

engine.addEventListener("render", render)

`ImGui.PopFont()`

Pops a font.

Example:

function render()
         ImGui.PushFont("VerdanaBold", 32)
	ImGui.Begin("mymenu", ImGuiWindowFlags.NoTitleBar)
        ImGui.Text("This is written in Verdana Bold.")
        ImGui.End()
        ImGui.PopFont() --This is important here
end

engine.addEventListener("render", render)

`ImGui.GetTexture(name)`

name - The name of the texture.

Returns a pointer to a IDirect3DTexture9. This can be directly used wherever the ImGui lua bindings expect a texture. For example ImGui.Image

Custom Textures

Custom Textures can be loaded the following way:

Locate the directory C:\Users\your user\Anvil
Create a new directory called texture_assets
You can store any images of format .png, .jpg or .jpeg in this folder
The name of each file will be the key which you pass to ImGui.GetTexture

Custom Textures Example Scenario

Suppose you put a file called icon.png into the texture_assets directory. To get access to this image as a texture that you can pass to other ImGui functions, do the following:

ImGui.GetTexture("icon")

Full Example:

function render()
	ImGui.Begin("mymenu")
        ImGui.Image(ImGui.GetTexture("icon"))
        ImGui.End()
end

engine.addEventListener("render", render)

`ImGui.BeginMenuBar()`

Begin a menu bar.

You will have to pass the ImGuiWindowFlags.MenuBar flag to the ImGui.Begin

in order to see the menubar!

`ImGui.EndMenuBar()`

Ends a menu bar.

`ImGui.BeginMenu(menuName)`

menuName - The name of the menu.

Begin a menu.

`ImGui.EndMenu()`

End a menu bar.

`ImGui.MenuItem(label, shortCut, selected)`

label - The label of the menu item
shortCut - Shortcut.
selected - If the menu item is selected.

Example:

local mOpen = false
local mSave = false

local function render()

	ImGui.PushStyleColor(ImGuiCol.WindowBg, Vec4:new(0, 0, 0, 1))
	ImGui.Begin("lua window")
	if (ImGui.BeginMenuBar()) then
		if (ImGui.BeginMenu("File")) then
			mOpen = ImGui.MenuItem("Open", "", mOpen)
        		mSave = ImGui.MenuItem("Save", "", mSave)
			ImGui.EndMenu()
		end
		ImGui.EndMenuBar()
	end

	ImGui.End()
	ImGui.PopStyleColor(1)

end

engine.addEventListener("render", render)

`ImGui.SameLine(offsetFromStart, spacing)`

Use this to have the next ImGui Element on the same "line" meaning vertical position.

offsetFromStart - align to specified x position
spacing - horizontal spacing amount in pixels

Example:

function render()
         ImGui.PushFont("VerdanaBold", 16)
	 ImGui.Begin("mymenu")
         ImGui.Text("Hello WOrld.")
         ImGui.SameLine(0, 16)
         ImGui.Text("I am written on the same line.")
         ImGui.End()
         ImGui.PopFont() --This is important here
end

engine.addEventListener("render", render)

`ImGui.Image(texture, size)`

Renders a texture with the given size.

texture - The texture to use. Use ImGui.GetTexture to obtain a texture.
size - The size of the image as a Vec2

	 ImGui.Begin("mymenu")
         ImGui.Image(ImGui.GetTexture("superman"), Vec2:new(128, 128))
         ImGui.End()

         ImGui.End()
         ImGui.PopFont() --This is important here
end

engine.addEventListener("render", render)

`ImGui.calcTextSize(text)`

Returns the size of the given text in the context of the currently used font as a Vec2.

text - The text

Example:

function render()
         ImGui.PushFont("VerdanaBold", 16)
	 ImGui.Begin("mymenu")
	 local text = string.format("Hello my name is %s", "Jeff")
