I am making a game for which i want to create a 3d room editor ,but i m unable to get the object's x,y,z postion ,,i only just select it ,,please help...

Explain better - what do you mean you're unable to get those variables? You can get them like any other object/instance.

Selecting a model means ,with the help of cursor clicking on 3d model on screen ,
as i am making a room editor ,i want to get object properties like its x,y,z,tex... values to put it into a text file..
i think u will understand...

So you need a method to find the instance(s) under the cursor.

If it's sufficient to check for objects of similar shape to the simple shapes (block, cylinder, ellipsoid, cone, wall, floor), you could use my Line–Shape Collision scripts combined with Yourself's mouse conversion script, and loop through all the selectable instances in view^#.

For example create an object that will be a parent for every selectable object, then for this parent construct a with loop, which checks for the mouse ray collision (in 3D space the mouse position spans a ray of points perpendicular to the 'screen') when a mouse button is pressed. if the collision script returns true, save the id of the instance to some global variable. After the loop this variable will hold the id of a selected instance, which will be used to call the object properties you need.

However, there will probably be times when you have more than one object under the mouse: you want to get the id of the first that comes in the direction of the mouse ray. For this, you can get the points of intersection and compare which one is nearest on the ray (I have extended my scripts to calculate the point of intersection). If I recall correctly, my Line–Shape Collision Example features a system that gets the id of the closest instance.

However, if the objects are arbitrary kind of models, you can use e.g. this DLL to raytrace.

Try drawing each model in a diffirent color, and then check what color is under the cursor when you click. Thus you will know what object has been clicked on. I belive filulius hade some example of that around here.
