How do I stop this Dash/Air Dash from being infinite?

I'm messing with this code I got from someone's tutorial long time ago and once "implemented" cannot make it not being infinite, basically the player

can spam it and fly forever. I just want sort of a cooldown while "on floor", and only one dash while "on jump/fall" until the player lands.

Sorry I supose is a very basic question for you guys but I'm barely starting to get in seriously with this great engine.

This is how it looks, please if someone can guide/help me will be great! Thanks!

To prevent the player from doing more than one Dash:

Add a boolean instance variable to the Player object called CanDash, set it to true initially

Add a condition to the Dash event: Player.CanDash is true

Add an action to the Dash event: Set Player.CanDash = false

To re-enable the Dash, on landing:

[c] Player On landed

[a] Set Player.CanDash = true

To re-enable the Dash, when on the floor:

[c] Player.CanDash = false

[c] Player Is On Floor

[a] Wait DashCooldownTime seconds

[a] Set Player.CanDash = true

Alternatively, you could look at using the Timer behaviour for re-enabling the Dash
