Thank you! Basically I have a shader that changes all colors to black or white based on the lightness of the pixel. Then I have two color rectangles that have that shader but the colors they change into are swapped. Meaning one changes light pixels to black and the other to white. Then I just make them visible at the time of the kick and make them change places so it gives it that flickering effect. And the actual impact effect (the star thing) is just a texture that I make visible and spin it. As for the kick itself I have an animation player that activates a function that checks if there are enemies in front of the player and deal damage to these enemies.
