Input Elements

All input elements allow for the XML UI to interact with the Lua scripts in the game instance.

Tip

Be sure to check out the UI section of the Lua Scripting API for how to receive the input from these element types. With Lua scripting, you can even modify the UI elements!

Targeting Triggers

When using an attribute that triggers scripting, like onValueChanged or onClick, the UI will target a default location. Global UI targets Global script, Object UI targets the Object's script. This behavior can be overwritten. For example:

<Button onClick="uiClickFunc">Click Me</Button>

If this was in the Global UI, this would trigger a function in the Global Lua script function uiClickFunc(). But if you want to target a function on an Object's script? Place the GUID for the object before the function name, like so:

<Button onClick="aaa111/uiClickFunc">Click Me</Button>

Now when the button is clicked, it will still try to activate function uiClickFunc() but it will try to do so on the Object Lua script of the Object with the GUID of "aaa111".

<Button onClick="Global/uiClickFunc">Click Me</Button>

And if this was in an Object's UI, it would direct the function activation to Global instead of that Object.

Remember you can also use the Id attribute to identify which UI element triggered the function.

Element Details

InputField

A text input for single or multiple lines. Is able to send the text (during edit and when finished).

Attribute Name	Description	Type / Options	Default Value

placeholder	A string that is semi-visible when there is no text in the input.	string	(none)
interactable			`true`
colors			`#FFFFFF\|#FFFFFF\|#C8C8C8\|rgba(0.78,0.78,0.78,0.5)`
lineType		SingleLine MultiLineSubmit MultiLineNewLine	`SingleLine`

Button

A button. Is able to send a trigger event.

Attribute Name	Description	Type / Options	Default Value
onClick	When clicked, a Lua function with this name will be triggered.	string	(none)
interactable			`true`
colors			`#FFFFFF\|#FFFFFF\|#C8C8C8\|rgba(0.78,0.78,0.78,0.5)`
textShadow			(none)

Tip

onClick passes nil for the value by default. However, you can assign a string that will be passed in onClick.

<Button onClick="clickFunction(stringName)" />

The above example passes a string with the name of "stringName" to the Lua function for the value property.
