Slow Motion HELP please!

FirstDan

Hi ALL

I want to add a slow motion power up in my game, i have some actors that interpolate horizontally and in a wave. All i want to do is when you activate the slow motion power up the actors would slow down.

Guidance or an demo would be greatly, greatly appreciated.

You'all rock/

If you are using interpolate, you can either interpolate self.speed/velocity to a lower value if game.slowmo is true (otherwise, interpolate to a higher value) or you can interpolate the speed for a longer duration when game.slowmo is true. I would go with the former because the latter would mean that eventually the actor speeds up to normal speed even when game.slowmo is true.

@tatiang - thanks for your reply, i put a display text behaviour on my moving actor and the self.linear velocity x was = 0. Confused to why its zero?

Its 0 because interpolate isnt a physics behavior. In other words it doesnt apply phyics to the actor to move it. Thats why you can interpolate an actor even if moveable is unchecked in it.

For speed, I think you'd need to do distance divided by time. So change attribute self.InitialX to self.position.x (put this at the top of the actor's rules) and then Display Text (self.position.x-self.InitialX)/self.time. You'd probably want to use floor, ceiling, or precision with that.

@JohnPapiomitis - ha ok, learned something new today! In this case would I need to slow the duration down within the interpolate behaviour to achieve slow motion?
