Deceleration

keekee312

Hi, I tried to make actors slow down when a button is pressed but it does nothing and I don't know why. I put a boolean when the button is clicked => For 5sec : DECELERATE is true

and in each actor : when DECELERATE is true... (and now i tried to change velocity, drag, apply a max speed etc but nothing works)

Thank you

maybe try using an acceleration behavior. For the angle use VectorToAngle(self.linear.X,self.linear.Y)+180 so that it accelerates in the opposite direction of motion. Use it in a timer.

Never tried this but it's worth a shot.

synthesis

Trying using an interpolation behavior that increases DRAG. Drag is similar to "wind resistance" and the higher it is...the harder it is for the actor to move/accelerate. Think of it as brakes.

So...when decelerate = false >>> accelerate (is on) and drag (is small)
otherwise >>> accelerate (is off) and DRAG interpolates to self.dragMax over 5 sec.

Make sense?

@synthesis : Great !! It works BUT it slows down actors which are already falling down but actors which are just spawn are stuck to the top of the screen, how can I fix that please ?

@scitunes : Thanks I'll maybe try this

Thanks for your quick answers

Finally it works.

When DECELERATE = false
=> accelerate : 300

otherwise : accelerate : 50
After 5 sec = decelerate = false
