Help moving a object with the mouse

[Rick]

Hello,

I need some help on making an object follow the mouse pointer.

I want to be able to left click on an object and it will follow the mouse pointer. Upon a second left click or right click of the mouse it will stop following the mouse pointer.

Thanks,

Rick

* User clicks with Left Mouse Button on Active
- Active: add 1 to Alterable Value A

* Active: Alterable value A = 1
- Active: set Xpos to Xmouse
- Active: set Ypos to Ymouse

* Active: Alterable value A = 2
- Active: set Alterable Value A to 0

An alternative to popcorn's method:

first change the hotspot of the object to the center

Then add the following events:

+User clicks with left mouse button on active
OR
+User clicks with right mouse button on active
-Active: Toggle internal flag 0

+Active: internal flag 0 is set on
-Active: set X position to XMouse
-Active: set Y position to YMouse

You're sure about that, Ketchup? Will this also deselect the object on a new click? =)

Collision mask permitting, yes it will. Toggle basically alternates the flag, so if it is off it sets to on and if it is on it sets to off.

Ahh thanks, I didn't know that
Hm, have that toggle thing always been there? Haven't noticed it before, lol

The toggle feature has been around since TGF. It was not in KNP because KNP did not have flags (only alterable value A, B and C).

theres no way to change hotspot position with event is it? and if you were to pick up a key or something then hotspot would be better in the center of the hole than middle of object..

You could always move the object relative to where you clicked on it:

* User clicks with left button on (Active)
+ OR
+ User clicks with right button on (Active)
- (Active) : Toggle internal flag 0
- (Active) : Set Alterable Value A to X( "Active" )-XMouse
- (Active) : Set Alterable Value B to Y( "Active" )-YMouse

* (Active) : internal flag 0 is on
- (Active) : Set X position to XMouse+Alterable Value A( "Active" )
- (Active) : Set Y position to YMouse+Alterable Value B( "Active" )

Here's my way of making it true drag and simulate moving the hotspot without the object jumping to the mouse.

On click on the object
+and flag 0 is off

-Set active's value A to mouseX - active's X pos
-Set active's value B to mouseY - active's Y pos

On click the mouse
+and flag 0 is on

-set off flag 0

While flag 0 is on
-Set active's X pos to mouseX - active's value A
-Set active's Y pos to mouseY - active's value B

I made it in KNP.
