Bounded Drag & Drop
The Bounded Drag & Drop behavior is an advanced version of the Drag and drop. This drags and drops objects either by mouse or touch with advanced bounding features.
Features include bound to either radius, position or both, bound by origin or edge and bound methods of clamp and halt.
The best benefit for this addon is that it supports all editors and runtimes of Construct. Both, Construct 2 and Construct 3.
It implements advanced bounding features for world objects.
Intstructions
1. The first step is to add the Bounded Drag & Drop behavior into an object in the project.
2. These steps are explained below. For more information, visit the Construct 3 Manual's behavior reference.
3. Do this by creating a world object (instance based), an object that is interactive with the layout, for example the Sprite object.
4. Select the object instance, then from the properties bar, click Edit Behaviors.
5. Once the dialog pops up, press the Add new behavior button.
6. A behaviors list dialog popup will show, with the list of available behaviors compatible with the currently selected object. If installed properly, the Bounded Drag & Drop behavior will be on that list.
7. Press add or doubleclick on the behavior, then it'll be added to the object's behavior list.
8. After adding the behavior, you will see the new object properties added by the behavior. You may refer to the Properties section below to learn more about these properties.
9. There are default properties similar with the builtin Drag & Drop, the Axes is the direction you can drag the object and the initial state determines if the behavior is initially activated.
10. Beyond the default properties, are the advanced bounding feature properties, I recommend reading the Properties section below to have insight on what feature each property does, and lookup the example projects to know how they interact with the objects.
That covers the basics, I wish you good luck on your learning!
Actions, Conditions & Expressions
Actions

Set Bound XYRadius  The radius in the X & Y axis it can move from its bound point. Both 0 is 'off'.

XRadius  The radius in the Xaxis it can move from its bound point. 0 is 'off'.

YRadius  The radius in Y which it can move from its bound point. 0 is 'off'.


Set Bound XRadius  The radius in the Xaxis it can move from its bound point.

XRadius  The radius in which it can move from its bound point. 0 is 'off'.


Set Bound YRadius  The radius in the Yaxis it can move from its bound point.

YRadius  The radius in which it can move from its bound point. 0 is 'off'.

Position :

Set Bound Position  The X location it can only move from its bound point.

Minimum BoundX  The Minimum Xposition it can only move from its bound point.

Maximum BoundX  The Maximum Xposition it can only move from its bound point.

Minimum BoundY  The Minimum Yposition it can only move from its bound point.

Maximum BoundY  The Maximum Yposition it can only move from its bound point.


Set Bound X Position  The X location it can only move from its bound point.

Minimum BoundX  The Minimum Xposition it can only move from its bound point.

Maximum BoundX  The Maximum Xposition it can only move from its bound point.


Set Bound Y Position  The Y location it can only move from its bound point.

Minimum BoundY  The Minimum Yposition it can only move from its bound point.

Maximum BoundY  The Maximum Yposition it can only move from its bound point.

Conditions
Default :

Is dragging  True if the object is currently being dragged.

On drag start  Triggered when the object begins to be dragged.

On drop  Triggered when the object is dropped (the drag stops).

Is enabled  True if the behavior is enabled.
Bound :

On any bound exceeded  Triggered when the drag is beyond any kind of boundings.
Radius :

On radius exceeded  Triggered when the drag is beyond any radius boundings.

Is radius exceeded  Triggered when the drag is beyond X radius boundings.
Position :

On position exceeded  Triggered when the drag is beyond any position boundings.

Is position exceeded  Triggered when the drag is beyond X position boundings.
Expressions
Bound :

BoundTo  Return to which point the object is bounded.

BoundBy  Return from which point the object is bounded.

BoundMethod  Return whether the object bound method is 'halt' or 'clamped'.
Bound Radius :

xBoundRadius  Return the X Bound radius length.

yBoundRadius  Return the Y Bound radius length.
Bound Position :

xMinBoundPos  Return the Minimum X Bound Position.

xMaxBoundPos  Return the Maximum X Bound Position.

yMinBoundPos  Return the Minimum Y Bound Position.

yMaxBoundPos  Return the Maximum Y Bound Position.
Bound Origin :

xOrigin  Return the Origin X of creation.

yOrigin  Return the Origin Y of creation.

The Bounded Drag & Drop behavior is also available for free from the Construct 3 and Construct 2 addon directory. There are also documentations and support there, although supporters have more priority.
