Thanks so much, ErekT!
I used Functions and Boolean variables to set the player's mechanics and movements.
Do you think that String variables is more effective?
It's worth emphasizing that my game mixes characteristics of the platform and beat 'em up genres. My character has several abilities such as attack, concentrated attack, combo attack, double jump, run, slide, climb and pick up impulse on the walls.
I confess that I had forgotten to apply the Delta Time to the platform states, but I'll test now.
Soon I'll tell you what happened here.
