Straight Forward Touch/Mouse Drag Offset? [Solved]

Hi there, I was trying to figure out a way to do a drag / offset so when i drag something it doesn't snap to center.

I found this thread scirra.com/forum/no-offset-drag-and-drop_topic47745.html but following the one available capx, it didn't work when I tried to reproduce it and all the while it struck me as oddly complicated to achieve the desired result.

Of course the capx out there works great, but when I tried to replicate it, it failed, but it was kinda complicated so I couldn't understand the need for having additional instance variables "mangle"? "mdist"? i don't understand what those names mean related to the offset..

I see the drag/drop behavior but it doesn't seem to address the idea of mouse offset.

So yea I just wanted to see if there was some straight forward approach to allow you to touch the lower corner of a dragable object and not have it snap to center but rather let you drag it from where you touch the object.

Thanks!

Off the top of my head...You can try storing the distance between the mouse and the object in private vars when it's clicked (by subtracting both x & y coordinates), then set the object position to the mouse minus those vars every tick. Of course you'd need a "picked" variable to decide if the object should be dragged.

The pin behavior would come in handy here since it accounts for offset, angle, etc. but I don't think you can pin an object to the cursor, and any object following the cursor lags so it won't be totally accurate.

Instead of using the drag and drop behaviour you could choose to do something like this.

give the object three instance variables, picked, offsetX, OffsetY

on object clicked

• set picked to true
• set offsetx to object.x-mouse.x
• set offsety to object.y-mouse.y

object is picked

• set object x to mouse.x+object.offsetx
• set object y to mouse.y+object.offsety

on mouse button released - object set picked to false

I'm on mobile, so I can't check the events inside construct atm, but it should be something like this.

LittleStain i follow this, but "object is picked". I can't find an action that matches that.

my attempt failed to result in a proper drag and i imagine the object is picked part is a big piece of it

Hey!)

Here, you forgot to set position of the object to mouse.position + offset)

PM'd you.

awesome thanks JJList and everyone for your input. This is great. I just know that offset/dragging will be something I need to use and this is a much more efficient way to achieve this effect

Thanks!
