Well, I got the time to dig in into the problem. The ‘action1’ is in an object, which is lost when I call the function, and the function also calls properties of that object with ‘this.’, that would pointing to that object, but ends transforming the ‘this.’ to the ‘keys’ object, which is not the intention.
If you want to see the code, this is the link project:

The keys object is in ‘scripts/game/character.js’ that have the ‘action1’ which is the jump(), and the keyPressed function is in ‘scripts/scenes/game.js’
