Defaults to 1.

`scaleY`

Video

`scaleZ`

Video

The Z scale (height) of the bot. Combines with the #scale tag to determine the final height of the bot.

Defaults to 1.

`scaleMode`

How the form is scaled to fit inside the bot.

Note that this setting does not affect #scale, #scaleX, #scaleY or #scaleZ. Instead, it changes how custom forms like meshes are scaled to fit inside the unit cube.

Also note that this setting affects a bot's collision volume. The collision volume will always try to wrap the bot's form to the best of its ability. This means that if you have a really large mesh the collider will scale up to surround the mesh.

Possible values are:

Value	Description
`fit`	The form is scaled to fit inside the bot's unit cube. The aspect ratio will be preserved. (default)
`absolute`	The form is not scaled.

`form`

The shape that the bot should be displayed as.

`iframe`	A webpage loaded into a 3D iframe. See `#formSubtype` for additional options.
`dimension`	The bot will display the dimension specified by `#formAddress`.
`portal`	The bot will display the dimension specified by `#formAddress`. This is an alias for "dimension".
`spherePortal`	The bot will display the dimension specified by `#formAddress` in a spherical manner, using the X and Y coordinates as latitude and longitude coordinates.
`cursor`	The bot will appear as a cursor in the multi-line editor. You also need to place the bot in the same dimension that the tag portal uses for the cursor to appear.
`codeButton`	The bot will appear as a clickable button in the multi-line editor when placed in the same the same dimension that the tag portal uses. The bot will also need a label in order to appear. The Start position of the bot the line number that the button should appear above, and the End position specifies the priority of the button compared to other buttons on the same line (larger numbers indicate lower priorities). Additionally, it is possible to display code buttons in the multi-line editor's context menu by setting the `#true` tag to `true`. In this case, the `#true` tag represents putting the codeButton in the code editor for every tag.
`codeHint`	The bot will appear as a hint in the multi-line editor when placed in the same the same dimension that the uses. If a `#color` is specified, then the code that the hint covers will use the specified background color. If a `#strokeColor` is specified, then the code that the hint covers will use the stroke as a box border around the code. If given a `#label`, it will be rendered before the start position. Use the `#[dimension]Start` and `#[dimension]End` tags to position the hint. Additionally, codeHint bots support the `@onClick` listener for when their label text is clicked.
`input`	The bot will appear as an input box in the menu portal. You also need to place the bot in the dimension that the menu portal is showing for the input to appear. You can change the type of input using the `#formSubtype` tag.

`formLightTarget`

The target of the light. Bot must have a #formSubtype of directionalLight or spotLight. Bot can not target self.

Possible values are:

Value	Description

Any Hex Color	Hex colors are three or six digit numbers that specify a color by its red, green, and blue components.

`formAddress`

The address that the bot should represent data from.

When #form is set to cube, skybox, sphere, or sprite, the address should be the URL of the image that the bot should display.

When #form is set to mesh and #formSubtype is set to gltf, the address should be the URL of the GLTF file that should be displayed.

When #form is set to iframe and #formSubtype is set to html, the address should be the HTML that should be displayed.

When #form is set to iframe and #formSubtype is set to src, the address should be the URL of the webpage that should be displayed.

When the bot is in the menu portal, this is the URL of the image or video that should be shown on the menu item. It can also be cube to show an icon of a cube, egg to show an egg icon, and helix to show an icon of a DNA helix. If the given value is not a URL or one of the predefined icons, then the specified Material Icon will be shown.

`formAddressAspectRatio`

The aspect ratio that should be used to ensure that the image/video from #formAddress is displayed correctly. Aspect ratio is the numerical ratio representing the width of an image divided by the height. For example, a 1080p image has a resolution of 1920x1080 which means it has an aspect ratio of 1920/1080 = 16/9 = ~1.7777777.

By default, CasualOS displays all images with an aspect ratio of 1. An aspect ratio of 1 ensures that the entire bot is covered, but if the original image has a different aspect ratio then it will appear distorted. To solve this, you can use the #formAddressAspectRatio tag to ensure that the aspect ratio that the image is displayed at matches the original aspect ratio.

Also note that negative aspect ratios will mirror the image horizontally.

Currently only supported by the cube, circle, and sprite forms.

The opacity of the bot's form. Allows bots to be semi-transparent.

Possible values are:

Value	Description
`1`	(default)
Any Number >= 0 and <= 1	The bot's form will use the given opacity.

`formRenderOrder`

It is not recommended to use this tag unless you are dealing with transparency issues caused by overlapping PNG #formAddress images.

Higher values mean the bot will be rendered first, and lower values means the bot will be rendered last.

Possible values are:

Value	Description
