unity 2d platformer dash attack.

In my code I have an object Player with a script PlayerMovement.cs attached to it. The enemy has a script EnemyHealthManager.cs with a public variable health that is equal to his actual healthpoint.

In my script PlayerMovement you have a function dash function, in order to adjust the parameter of your script change these variables:

speed is the speed of the player when he moves

dashSpeed is the speed of the dash;

dashCountThreshold is the treshold that currentDashSpeed has to underpass in order to stop dashing (dashCountThreshold must be < dashSpeed);

cooldownDash is the time to pass before pressing again the dodge button;
