Question

Mobile development

Hello!
I want to implement the following function: when a player enters an opaque texture (that is, into a Trigger), then it becomes transparent, and when it leaves the Trigger's field of action, it becomes opaque again.
Please help, thanks in advance!

Change the color property of the SpriteRenderer component. The Color type has 4 channels - red, green, blue and alpha (R,G,B,A). A is responsible for transparency. Accordingly , there will be a translucent sprite. When entering the trigger, we decrease the alpha channel, when we exit, we increase it. new Color(1f, 1f, 1f, 0.5f)
