Defining object zone

[GloriousIntruder]

Hi, I just recently started learning MMF2 and I am trying to create a game of drag and drop. So far I have been able to do dragging and dropping for an object. The problem is that the mouse pointer has to be exactly on top of the object when I drag it and when I move too fast, the object is dropped right away. The expression that I used is:

Condition:
Mouse pointer is over OBJECT X
+ Repeat while left mouse-key is pressed

Action:
Set X Position to XMouse
Set Y Position to YMouse

My question is that how can I hold the object and drop it only when I release the mouse button. I appreciate the answer!

Hey, and welcome!

Here is a method that does what you want AND makes sure the object doesn't reposition itself to the mouse, but remains its position when you click on it.

* user clicks with left button on OBJECT
- OBJECT: set alterable value A to xposition of OBJECT - XMOUSE
- OBJECT: set alterable value B to yposition of OBJECT - YMOUSE
- OBJECT: set flag 0 on

* [NEGATE] Repeat while lefy mouse key is pressed
- OBJECT: set flag 0 off

* OBJECT: flag 0 is on
- OBJECT: set xposition to alterable value A + xmouse
- OBJECT: set yposition to alterable value B + ymouse


To negate a condition, right click the condition and select Negate.

Thank you so much for the answer!

No problem, Glorius Intruder!

A while ago, I made a rather interesting example file of how to drag active objects. You may find it useful, now or in the future.
