How to Create Invulnerability Frames in Unity about aleksandrhovhannisyan.com HOT 7 OPEN

just wanted to say thanks for this post! super helpful, and very clean and understandable code. This was a great alternative to the spaghetti mess I had created, and I love the way you handled the blinking effect, even if that's not how I'm doing it in my game (changing the material instead of the scale, but it works fine if I follow your steps)

this was really helpful to me, thank you

though Im having an issue with the model scale in the flash. Somehow the scale increase after the flash and stay that way in the others, the video explains it better

@fede7218 What is your model's initial scaling factor? I'm guessing it's not set to 1, so ScaleModelTo(Vector3.one) causes it to become larger than its initial size once invulnerability kicks in. Instead of scaling by one, it may be better to read the model's initial scale and alternate between zero and that value.

@stilestr Glad it helped! And that sounds like a clever solution—I hadn't considered that, but it's probably much safer than scaling the model.

This works really well in my 2D Platformer but unfortunately when I ran the code in Unity in 2D my player sprite falls through the floor when he gets hit and flashes. I'm wondering how it can be tweaked so that the sprite doesn't fall through the ground when he takes a hit but can still phase through enemy sprites

@Morkhelt Hard to say, but my article cautions that you should scale the sprite and not the entire character model; scaling the latter can break collision detection, which I suspect is what is happening here.
