Dragging stuff.

[Paul_Boland]

Hi Folks.

Does anyone have an example of how to drag stuff around the screen in an iOS App? I have a few ideas in my head on how to implement it but before I go doing a load of testing I decided to check and see if anyone already has an example on offer?

Have you tried the Drag&Drop movement? It should work.

[Paul_Boland]

I'll give it a try, thanks.

It would be nice if there was an easy way to make things drag things around and have them carry on with deceleration.

Where can I find the "Drag&Drop movement"?

I have created a windows application using the drag object but would like to export the program as iOS App.

Thank you.

Select the object that you want to drag and drop, then on the "Movements" tab of the objects properties pane, choose drag and drop as the movement type.

Thanks! That works great and simplifies the events needed.

Ah, like momentum? Shouldn't be too difficult to do, just record how far it moves horizontally and vertically each frame and store them in values, then once the dragging stops, create your own inertia from that value and then decelerate it by subtracting from the value until it reaches zero.

I tried that but it only carried on in the direction that it is away from the start position, so if you let go of it while going towards the start position, it would carry on in the direction that the active is away from the start position.

Hm, you're allowing negative values? You're not using Abs() or anything like that?
