Character Dashing

Three things I want to learn how to do.

1) Have my player dash with a button.

2) Have my player dash while pressing the direction twice.

3) Have my player be able to air dash.

I understand that I can have my player move forward in x amount of pixels with the move forward feature. The thing is that I want my character to be able to have it flow like megaman x or something sort of that caliber. The move forward function actually has my player sort of jump to the pixel or teleport, what have you.

Any tips would be great.

You can temporarily increase the player's acceleration and max speed and have it reset on a timer.

For the double-press dash, I would have an instance variable on the player titled "Dash". Make it so pressing ">" once adds 1 to "Dash" and subtracts 1 from "Dash" a second later. If "Dash">1 then activate the effects you want and set Dash to 0.

It should work identically in the air if you disable gravity and cancel out Y velocity on the same timer.
