*** Tempest's BUILD Tutorial ***
Lesson 2 : Making doors that move up
=====================================================================
Purpose:
A tutorial on making doors that move up in Duke Nukem 3D using
Build.
Step 1:
Make a door opening. Choose some cool textures.
Step 2:
Move the ceiling of the door to the floor. Do this by aiming at the
wall or the ceiling of the door sector and pressing PgDn. If you
want the door to open without the walls also moving, press 'O' on
the sides of the wall. You'll notice that when you move the ceiling
up or down, that the walls move differently. In fact, they don't
move at all anymore.
Step 3:
Now that you have moved the ceiling of the door sector all the way
down to the floor, we're ready to make the door work.
Step 4:
For a door that opens up by moving upwards, you have to give the
door sector a Lo-tag value of 20. Do this by going to 2D-mode,
moving the mouse cursor to the door sector, press 'T' and then
enter the value "20". You'll see a white rectangle within the
sector with the text "0,20" in it. That's it!
If you want the door to make a sound, insert a Music & SFX sprite.
Insert a sprite in 2D-mode by pressing 'S'. In 3D-mode you'll have
to point to the floor and then press 'S'. Press 'V' twice to
get a listing of all sprites. Select the blue M, that's sprite #5.
You can press 'G' to select the sprite# to jump to. Move the
sprite inside the door sector and give it a Lo-tag value of 166
or any other sound you want for the door. Giving sprites a Lo-tag
value requires you to be in 2D-mode, moving the mouse cursor on
the sprite and then press 'Alt-T'.
Give the door a certain speed by adding a Speed-sprite (sprite#10).
It's Lo-tag value must be the speed of the door. I used 256 in
my example map.
You can make the door close after a while by adding a Sector
Effector sprite (sprite#1). The Lo-tag value must be 10. The
Hi-Tag value must be the time that the door waits before closing.
Give the SE (Sector Effector) a Hi-tag value by pressing 'Alt-H'
in 2D-mode.
