You would need to use image points x,y or overlap or pin an invisible sprite to the bottom and use it as your on overlap condition trigger.

So i have to create another invisible sprite to each side of the box? is there an easier way? since doing it like this could lead to some more problems...

So I Tried to make a box that triggers certain action when it collided with other object on a certain side (bottom side will stick with object A, top side will stick with object B, etc)

but the problem is i can't find where to assign "when collision on x side with other object, do this" thing, i only found "when collided with other objects, do this". No sides of the collider specified.

is there a way to specify a certain specific sides of the collider to trigger collision?

Thanks

so i'm currently trying to make a game which involves stacking sprites (in this case, boxes) on top of each other by catching them, you can get the sample i made here

1drv.ms/u/s!Audt-JfwoahjgaQrue7FkKkceORmiQ

in summary, this is what i did :

• generate the box on top of the canvas
• when the box came in contact with the player or another box, it pins to the object it touches (in order to stick the box to the other object)
• when the "stack" reaches 10 boxes, destroy the stacked boxes

what i want to do :

• how to make the box fall off when it only touches less than half of the box's width? i tried with the physics but doesn't work at all

Yes, i know i'm not good at explaining and my english is not that good as well. So if there's something unclear just ask, I'll be glad to provide more information regarding this problem. Thanks
