[SOLVED] Using the mouse button to move an object to another position.

[charcoal]

 I am wanting to use the mouse to move an object in the xyz axes. I have created an object and added Get Mouse Button Down, Mouse Pick and Set Position. When I mouse click the screen to move the object to another position it moves to 0,0,0 in world space. I want the object to move to the postion where the position of mouse is when clicked on screen in xyz world space. I have created a variable called clickedPosition with vector3.

Take a look at the PlaymakerSamples\TestLab\Input\ClickMoveTo sample scene.

Does the object you're clicking on have a collider?

Hi Alex,

Yes the object does have a collider. I want to click and drag the object anywhere in world space. I do not want to use a plane for the object to move on. I will have a look at the example you mentioned.

Did the example help?

Not sure what you mean... you have to translate the 2d click position into a 3d world position. Typically you use Mouse Pick or Raycast to get a 3d position in the world. The world can have any number of colliders, including Mesh Colliders, so you can make pretty much any clickable surface shape you want...

I think his ground is going to be either a terrain or some sort of non flat surface.

Hi Alex,

Yes I got the object to move along a plane using the mouse button. However I want to remove the plane altogether from the scene, and have the object move in world space all by itself using the mouse button. It seems I can only move an object if there is another object in the scene which it uses as a surface to move on.

You could use Screen To World Point:

You can use the mouse position for screen x and y, and some fixed distance for z. This moves the object on an imaginary plane in front of the camera... Is the what you're looking for?

Hi Alex,

Screen to World Point is working, thanks. But each time I click to move the object it comes closer and closer to the camera and then it eventually it disappears. Also the object only moves if I click on the side of it, and I would like to smoothly drag it to another location. Any suggestions how to solve these problems would be appreciated. Ultimately I want to be able to create an multiple objects in world space with a click of the mouse, and then select them and move them about.

I have got the object now moving freely in world space using Screen to World Point and Set Position. In Set Position I have set the Z vector to -5 to stop the object moving closer to the camera each time I click the mouse button. I have one problem left where I want to be able to click and drag the object, but I seem to be only able to click and place the object. Can anyone help?

Hi,

 Two options, depending on if you want to use physics or not:

Thanks Alex and Jean, it is working nicely now.
