Quick Start

Let’s add a blinking effect to our game object.

In the knight demo we have a game object with a sprite renderer.

Now we need to add DamageEffectScript component on the same game object where the sprite renderer is.

As you can see now we need to set blinking material

You can select one of the preset ones, or a custom made. We want to use it on 2d sprites, that means we need to select from materials that are represented as sprites, not as spheres. Note that preset 3d materials have “3D” postfix in their names.

As another option you can just drag and drop material you like from the directory Assets/DamageEffect/Materials where they are conveniently placed in separate folders.

Now all we need is to add script that triggers blinking effect

Not much to explain here except for the Blink method.

Blink method accepts two parameters: first is delay before blinking in seconds, second is duration of blinking.

Well, that’s it!

FAQ

Q: Where are my shadows?

A: Use DamageShader3D_UnityLambertBase AKA DamageBlink3D_UnityShadows

Q: How exactly does blinking script work?

A: Blinking script is fairly primitive. It seeks all the renderers down the hierarchy, saves current materials, replaces current materials with blinking materials and starts a coroutine with delay. When the coroutine ends it restores old materials to the respective renderers.

Q: Blinking script doesn’t work. What can be the cause?

A: The issue can be that materials don't restore. That can happen if old materials weren't available at the Start event. Also it could happen if coroutine was interrupted, it usually happens when gameObject with coroutine was disabled/enabled during the coroutine execution, it kills current coroutines. For concrete cause I'd debug the blinking script and check what happens with old materials in BlinkCoroutine.
