This #unity tutorial demonstrates how to create a "slide to accept" button using a UI slider.
The video covers the following steps:
Setting up the UI Slider (0:11-0:47): The tutorial begins by creating a UI slider, adjusting its width and height, and ensuring its children expand to fit the parent.
Handling Slider Value (0:54-1:07): It explains how the slider's value, ranging from 0 to 1, will be used to determine if the "button" has been clicked or accepted.
Scripting for Color Change (1:11-4:57):
A C# script named Slider Color Change is created and attached to the slider (1:11-1:16).
The script references the slider, a desired fill color (green in this case), and the fill image (1:22-1:51).
An OnValueChanged event listener is added to change the fill image's color from its original color to the new color as the slider moves (2:14-4:57).
Implementing the "Accept" Logic (5:01-7:25):
An if condition is added to check if the slider's value reaches its maximum (1), triggering an "event triggered" debug log (5:01-5:44).
The slider is then disabled to prevent further changes after the event is triggered (5:51-7:25).
Adding Visual Feedback (Checkmark) (7:26-9:20):
An image of a checkmark is added to the UI (7:33-7:50).
The script is updated to hide the checkmark at the start (8:06-8:15) and display it once the slider reaches its maximum value and the event is triggered (8:18-9:20).
