moving objects with mouse

Hiya,

Just a couple of quick questions regarding moving objects with the mouse.

The code i have to do this is as follows :

Mouse Left Button is down   object   set position to (mouse.x,mouse.y) object pick instance with UID

        object.UID

Mouse   Cursor is over object

now firstly when you move the object with the mouse it is very easy to leave it behind if you move the mouse too fast, is there a way to have the object latch onto the mouse cursor so this doesn't happen?

secondly when you move the object over another object (of the same type) one of the objects disappears.

and finally if you declare two different objects with similar code to above then when one object is moved over the other object, they latch on.

Any help would be appreciated, thanks in advance

hi thanks for the response, i am kinda new at this stuff, what do you mean by set selected to True?

k so this is what i've got :

set a boolean variable to the object

Mouse on left button click   object   set variable as true

pick instance with UID

        object.UID

Mouse   Cursor is over object

Mouse Left Button is down   set position(mouse.x,mouse.y)

pick instance with UID      set variable false

        object.UID

it works quite well BUT, as soon as i click one of the objects, the instances of the object all disappear...weird?

you dont need the uid, if you use the on object clicked, that object will be picked, in the same event you set the boolean "selected" of that object to true

object boolean selected is true set position to mouse

Mouse: [invert] left button is down > means when you release the mousebtn

set selected to false
