i want an actor to follow my touch (move to where i touch the screen) without me having necessarily to be touching the actor. i tried to do: move to x=devices.touch.x and y=devices.touch.y (something like that) but the actor stoped following my touch when it reached the touch x and y postion.

Do you know how to fix this?

    I'll help even though I'm not TSB. :D

    Try Constrain Attribute instead of Change Attribute.

    try doing using magnitude to determine a distance between the touch location and the actor and then constrain the velocities based on that and use max speed to keep it from going faster than your want. then when you touch it would move toward what ever point you are touching but then if you move your finger it will change directions. or speed up a little. I'm feeling a bit generous today. I may go ahead and make a demo of this if I can squeeze in some time.

    Here give this a try and see what you think. It will continue to follow your touch to where ever it goes and it speeds up as you get farther way and slows down when its close to the touch. Also when you stop touching it will stop where it is.

    That's really nice. What I like about this demo is the simplicity. I would have created a new attribute and constrained it to the magnitude blah blah blah...

    This is a good reminder that there is often a simple way using simple math to do some pretty cool stuff.

    Thanks Scitunes,

    I actually started to go that route but then I realized using magnitude will give me only one even number and if I put that number into both x and y velocities it will just move at 45 degree up and to the right.

    So I basically broke up the magnitude expression to find a value for x and a value for y.

    Also this is a good display of how linear velocity x and linear velocity y are related to a 90 degree triangle. I hate to go off in a lecture, but understanding these things will help with being more creative in how people can accomplish a task.

    I would be lying if I said part of me just wanted to show him TSB is not the "only" person on the forum that can help with his problem. ;) Although since i'm also TshirtBooth I guess TshirtBooth really is the only one that can help. ;)

    This thread is weird
    according to tshirtbooth, there might be 6 billions of people name "tshirtbooth"
