[quote="DtrQ":rmcok5mw]There is only issue with behaviors. Low FPS makes platform jumping higher and high FPS makes jump lower[/quote:rmcok5mw]
As Mipey says, it should be time delta'd so that there's no difference whatever the frame rate.
But it does bring me back to my original comment.
If a behaviour does what you want, how you want, then there's no reason not to use it.
If it doesn't, down to the behaviour not working as it should or it's poorly written, then it should be avoided.
Bad code is bad code, whether it's written by you or someone else.
