Animating Direction When Constrained to Mouse Y

Hi all,

My latest challenge...

I've got an actor constrained to a MouseY integer, so that when the mouse/finger is moved up/down the actor follows.

Is there a way to change the image/animate it when moving left or right?

I realise self.motion.linear velocity Y > 0 won't work??

Regards

Tim

    @Tim_A You could use the trick constrain self.motion.linear to 10*(mouse position-self.position).

    If it doesn't work well for your actor you could have this hidden to just change the states.

    Edit* Made a quick demo project for you.

    Wow thank you for that :)

    That's a great effect, and will be very useful for another game i'm building too!

    There's a bit of a lag between the actor follow and the mouse position... can that be tightened up or is it a quirk of the approach?

    Thanks again, much appreciated.

    Yeah it can be tightened up try changing the 10, i thought you could have the animation rules in here and still use your original code to move/constrain.

    Have a game integer or boolean for up so if up is true…..and use this to work out if up is true but have its alpha down to 0 so you can't see it…well that was my thinking behind it :)
