Moving an Actor via Touch on screen

imperiousdev

Hi,

I have an actor in my game that I need to move depending on the users touch (user touches left side of screen, actor moves left, user touches right, actor moves right etc).

I have rules set up already which works for a keyboard arrow button and also the accelerometer But i cant seem to get the touch working.

I assumed it would be " Attribute game.Touches.Touch 1.X < -0.1 to make him go to the right.
But that doesnt seem to work.

Probably not the most elegant solution and I'm sure others will have better advice, but when I was working on something with a similar control scheme, I simply created two invisible actors, one for the left side of screen, one for right, and then said if either were touched, the actor would move in the appropriate direction.

Above a perfectly good way of doing it. Worth adding rules to cancel control on both buttons being pressed, and if you are putting in scrolling put the buttons in a non scrolling layer so they stay with the camera.

you could do what he did, or you could say if the x is less then 240, or whatever half the screen is, then move left, if its greater then 240, then move right

have x be the position of the touch, there should already be an attribte called touch position i thin

Ah ok, thanks guys. A couple of ways to do it for me to consider there. I have the accelerometer control method implemented, just not sure if that is enough. I personally prefer games with touch controls.

I shall have a play with the suggestions and get back if I fail

Thanks all
