Here is a c3p file with an Immovable Base object with 4 Immovable Boxes and 1 Movable Box on top of the base object.... (all with physics behavior)

https://drive.google.com/file/d/1leaFHXzUFm5TGhHXtn4HIRULd2BCIJUI/view?usp=sharing

Movable Box also have Drag & Drop Behavior

When you drag the movable box around Immovable boxes you will notice that it behaves weirdly.

How do i stop it in a way that player can easily drag the movable box and fit it around immovable boxes easily, without it behaving like crazy?

Set a tick - to prevent rotation on the box. and it will not spin.

But I dont want to prevent rotation i still want it to behave as a physics object while i am placing it on other blocks...

Edit : I also want the blocks to act as real, they go into each other/ through each other when i drag them, i want it to stop when it hits other block.

yeah i see you removed unmovable property from unmovable blocks, i want them static.

Enable collisions with all objects, and do this.

Hey can you look at this file

https://drive.google.com/file/d/11QebDf79f9nxSHjjDYEyMkLgQlf7ihLk/view?usp=sharing

How it should work : the Box should be immovable when overlapping at offset from other block

Problem : It is only working with two sides... Top & Left But not with Right and Down side.

From the official manual:

Therefore it is highly recommended to control Physics objects entirely via the Physics behavior (by setting forces, impulses, torques etc.), rather than trying to manipulate objects by Set position, Set angle etc.

In short, don't mix Physics with non-physics behaviors and actions! You can control a different (invisible) sprite with Drag&Drop behavior, and move your Physics sprite to its position with physics action. Here is a demo:

I'd add that physics is a pretty closed system and adding stuff like drag&drop won't be properly handled by the physics. Well it does sort of work to some degree at least.

Hey i checked out your example, thanks for that!

But the reason i wanted not to use drag and drop behavior was because i wanted to lift the boxes without directly touching them (see the capx)

drive.google.com/open
but i cannot achieve that with drag and drop, is there a work around for this such that i would work well with physics?

You can try the same principle as in my capx - move the physics object towards target position with Set Velocity, Apply Force or Apply Impulse actions. The important thing is not to use Physics and Drag&Drop (or other behaviors) in the same object.

Here is another example, the code is pretty messy, you basically only need event #13:

I succeeded in moving the box with just physics, but the Overlapping Problem Still Persists...

Can you solve the overlapping thing please?
