Transition Options

Within a selectable componentA functional part of a GameObject. A GameObject can contain any number of components. Unity has many built-in components, and you can create your own by writing scripts that inherit from MonoBehaviour. More info
See in Glossary
there are several transition options depending on what state the selectable is currently in. The different states are: normal, highlighted, pressed and disabled.

Transition Options: Function:
None This option is for the button to have no state effects at all.
Color Tint Changes the colour of the button depending on what state it is in. It is possible to select the colour for each individual state. It is also possible to set the Fade Duration between the different states. The higher the number is, the slower the fade between colors will be.
Sprite Swap Allows different spritesA 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info
See in Glossary
to display depending on what state the button is currently in, the sprites can be customised.
AnimationA collection of images that create a moving image when played sequentially. In Unity, an animation is the result of adding two different animation keys, at two different times, for the same animatable property. More info
See in Glossary
Allows animations to occur depending on the state of the button, an animator componentA component on a model that animates that model using the Animation system. The component has a reference to an Animator Controller asset that controls the animation. More info

must exist in order to use animation transitionAllows a state machine to switch or blend from one animation state to another. Transitions define how long a blend between states should take, and the conditions that activate them. More info

is disabled. To create an animation controller click on generate animation (or create your own) and make sure that an animation controller has been added to the animator component of the button.

Each Transition option (except None) provides additional options for controlling the transitions. We’ll go into details with those in each of the sections below.

Color Tint

Property: Function:
Target Graphic The graphic used for the interaction component.
Normal Color The normal color of the control
Highlighted Color The color of the control when it is highlighted
Pressed Color The color of the control when it is pressed
Disabled Color The color of the control when it is disabled
Color Multiplier This multiplies the tint color for each transition by its value. With this you can create colors greater than 1 to brighten the colors (or alpha channel) on graphic elements whose base color is less than white (or less then full alpha).
Fade Duration The time taken, in seconds, to fade from one state to another

Sprite Swap

Property: Function:
Target Graphic The normal sprite to use
Highlighted Sprite Sprite to use when the control is highlighted
Pressed Sprite Sprite to use when the control is pressed
Disabled Sprite Sprite to use when the control is disabled
