Introduction
All buildings within a Virtual World consist of different more or less complex 3D objects which have been put
together like some kind of bricks. Thats true not only for houses but also for nearly everything which is visible and
imagineable inside a world: streets, places, whole cities, woods, parks and much more.
A user is able to create such things with the building-functionality easily. The basic principle of it is: know the
name of an object (e.g. "wall01_20m_grey.rwx"), put the object into a world and move it to the desired position.
But there are some restrictions. A user is only able to modify his own objects (except he has owner-privileges). So it
is impossible for him to right click (= select) an object of an other user and to (re)move it. Additional he is able to
build only if he has the building-privilege. Thats true at least in worlds with public building enabled. As a third point
it is not allowed to build beyond a worlds border.
Put a new Object into a World
If you don't have an own object near the place you want use to build (e.g. because you don't have build anything yet)
you have to create a completely new object. To do that, perform the following steps:
- Move to a position where you find enough space in front of you to let the object appear
- Bring the "Build" tab pane to front (it can be found on the left side of the main window)
- Enable the building mode (this can be done by selecting the check box at the lower end of the "Build" tab pane)
Please note: if this check box is disabled you are not allowed to build in this world and all steps declared here are
impossible for you
- Now you are in building mode, that means you can fly using keys "ALT" and "Page Up" or "Page Down"
and you can go through objects (collisions are disabled)
- If it is not already selected: choose "Standard Object" from the combobox at the upper end of the "Build" tab pane
- Enter the name of the object you want to have in the object name field below of the combobox on the upper end of the
"Build" panel and leave it using "Return" or the "Tab" key
- Now the build-button (symbolized by a small hammer) below of this input field should become enabled, press it to let
the object appear in the world
- The object should become visible now in front of you, go back some steps if you can't see it
Please note: If the object isn't available from your local cache it appears as a red triangle during download; normally
it should be replaced by the desired object after some seconds. If this doesn't happens it may be the object file is
corrupt or you entered a wrong object name.
Build by Copying Objects
If there is at least one own object near to you or if you want to build larger things out of the same object type you can
put objects into a world using the copy function. Following steps are neccesary:
- Right click the object which has to be copied, if you are allowed to modifiy it, it will be drawn as wire frame yet,
building mode will be enabled automatically by this action
- Press the copy button
- Now the originally selected object should be drawn solid again and the copied object should be visible as wireframe
near the original, shifted by 1 m in x- and z-direction
- The copied object can be replaced by an other one now simply by changing its name in the objectname textfield below
of the objecttype combobox at the upper end of the "Build" tabpane; finish this action with "Return" or "Tab"
- Equal if the object was renamed or not you have to conclude the operation by pressing the "Finish" button (the button
with the green hook, directly below the combobox); now it is visible as a new, solid drawn object
Place an Object
The building principles declared in the preceding sections show you how to put an object into a world. The problem is,
both methods put them to defined positions but from the point of view of the user they appear only "somewhere". That
means you have to move them to the desired locations afterwards. To do that the arrow buttons inside the "Build" tab
pane have to be used:
- Right click the object you want to move, it should be drawn as wireframe afterwards
- Press the flat arrow buttons to move the object in horizontal and vertical directions
- Press the round arrow buttons to rotate the object by its three axises
- If the object is located at the correct position the operation has to be finished by pressing the button with the
green hook (the "Finish" button)
Please note: The arrow buttons cause movement in defined stepsizes. These stepsizes can be changed by using the
radiobuttons "1", "2", "3" and "4" below of them. If smaller numbers are selected the
stepsizes are smaller, larger numbers mean bigger stepsizes are used.
Alternatively you can enter the absolute coordinates with a resolution of 1 cm directly. This can be done using the input
fields directly below the arrow buttons they belong to. But please note: all these actions are possible only when the
object is selected!
