Creating an Earthquake

NOTE: Please refer to the quake.map file when 
working through this tutorial.

1. In 2D mode, create a large sector (this will 
surround the area damaged by the earthquake). Put 
the cursor in this area, hold the left <Alt> key 
and press the <F5> key. Give this area a specific 
RX ID tag number (I used 111).

2. Next, create a separate sector that will simulate 
the area damaged by the earthquake. Put your cursor 
in this area, hold the left <Alt> key and press the 
<F5> key. Change this area's type to 600 : Z Motion, 
and give this area a separate RX ID tag number 
(I used 101). File out the pertinent data like so:

Type 600 : Z Motion
RX ID : 101

Trigger Flags:
x 1-Shot

OFF->ON:
busytime = 33
Wave 1 : Linear

ON->OFF:
busytime = 33
Wave 1 : Linear

Trigger ON:

x Enter (To start quake when step on sector)

or:

x Exit (to start quake when step off sector)

3. Go to 3D mode, place your cursor on the quake 
sector, hold the left <Alt> key and press the <F3> 
key. Now lower the quake sector to the depth you want 
it to sink, hold the left <Alt> key and press the <F4> 
key. Finally, raise the quake sector back so it is 
aligned with the surrounding area. You can place a 
sound effect sprite (#2520) in the quake area and 
give it the following data:

data1: 66
data2: 265

4. Place an earthquake sprite (#2072) in the sector just 
outside (or surrounding) the quake area. Give it an RX ID 
of the surrounding sector (remember, I used 111), and 
change its data1 tag to 700.

5. Save your map and exit. Now when you play your level you 
should have an earthquake. You can place Hidden Exploder 
sprites around the area to add the effect of explosions 
when the ground is sinking, or place so Gib Object sprites 
around to throw out garbage. If you do not know how to 
do this see the tutorial concerning EXPLOSIVE CRACKS in walls.
