Mirror Toggle

An example of setting up a mirror toggle via UI Button

• Add a VRC Mirror prefab, disable it to save performance by default

• Add a Universal Action to the Mirror object

• Make sure Active is checked, check Fire Object Toggles, click on the Game Objects List and click Add Element

• Drag your Mirror object into the empty field, select Toggle in the dropdown on the right

• Add a UI -> Button to your scene, set the Render Mode to World Space and scale it way down and place it where you want

• Add a Ui Shape component to the Canvas

• Change canvas layer to Default

• Click on your Button inside the Canvas and add a new On Click() event by clicking the small + icon in the bottom right

• Drag and Drop your Mirror object into the empty field that appeared

• In the dropdown next to Runtime Only select UdonBehaviour -> SendCustomEvent (its all the way at the bottom)

• Type Trigger in the text field

You're done! Now you can toggle your mirror via UI button in Udon.

The major thing to note here is to make sure that the component, and the game object its on, is always enabled if you're using the Delay parameter, otherwise it will never fire as the Update method will never be called.
