Drag and drop issue

alexxxhp

If you have multiple object with a drag and drop how do you keep objects from being drags along when you pick one of them up for example I have 14 items on screen for drag and drop when I pick one up and I go over another by mistakes it picks that one up as well and mixes them up. I want one picked up but the other not to react until I select them and drag them even if I go over them.

I have that same problem too, anyone have a solution?

it might have something to do with the whole mouse down options - try changing it to touch?

i would set a global boolean attribute called "isDragging" or something like that.
Leave it FALSE by default.

Only be able to pick up an object when isDragging is FALSE.

As soon as you pick up an object, set isDragging to TRUE.

As soon as you drop an object, set it back to FALSE.

Hope this helps!

And if I want the object to be dropped in a precise place when is over it (like a snap to grid behavior)?

I made a little demo project explaining this:

how can you make an actor return to the pick up point if dropped in the wrong location an example like I pick up an actor then drag if I let go in the wrong place the actor should return the original pick up point how can that be done.

You would have to have two attributes, homeY and homeX in the actor.

You could then have a global game attribute called "dropIsGood" or something like that.

Then in the actor, a rule that says:
When game.dropIsGood = FALSE
move to homeX, homeY

That's the basic Idea.
