Scripted Elevator
Contents |
Introduction
Scripting an elevator can be one of the most useful uses of the scripting system. There are two types of scripts: a specific script, which works only with the entities you paired it to and a generic script, which uses variables to apply to many entities. This page will explain both.
In either case here's what you need:
- A func_static with an origin brush
- A target_scriptrunner
- A trigger_multiple
- Several ref_tags
- BehavEd scripting program
Lets get started.
Specific Scripts
When you make a specific script, in BehavEd you make determinations based on the targetnames you gave your entities.
In-Game Entities
First things first, you need to name your lift. Set the following key/value on the func_static:
- script_targetname: scripted_lift
Next, on your target_scriptrunner set these keys/vaules:
- usescript: scripts/two_level_lift
- targetname: lift_runner
- count: -1
- parm1: 0
Now, on the trigger_multiple, set these keys/values:
- target: lift_runner
- spawnflags: 5
- wait: 10
For this example, the lift is only moving between two levels. Place two ref_tags, one at each level, in the position where the origin of the func_static will be. Set the keys/values on the upper one and lower one respectively as:
- targetname: lift_up
- targetname: lift_down
Now that the entities are set up, you need to make the script that will make them work.
Writing the Script
In BehavEd, you need to generate a script that looks like this (explanations in the comments; they are not part of the script):
if ( get( FLOAT, "SET_PARM1"), =, 0 ) //This conditional is how our lift goes to one level and stays there until it is triggered again. It runs these commands if and only if parm1 is 0.
{
affect ( "scripted_lift", /*@AFFECT_TYPE*/ FLUSH ) //The affect block is important, without it the script will run on the target_scriptrunner.
{
move ( tag( "lift_up", ORIGIN), 10000 ); //This tells the lift, which is starting at the bottom, to move up to the upper tag over a period of 10000 milliseconds, or 10 seconds.
}
wait (10000) //Wait until the lift reaches its destination...
set (SET_PARM1, 1) //...Then change parm1 on the target_scriptrunner from 0 to 1.
}
else ( ) //The else closes the conditional by running these commands if parm1 is any value other than 0.
{
affect ( "scripted_lift", /*@AFFECT_TYPE*/ FLUSH )
{
move ( tag( "lift_down", ORIGIN), 10000 ); //Works the same way as above except in reverse.
}
wait (10000) //Wait until the lift reaches its destination...
set (SET_PARM1, 0) //...Then change parm1 on the target_scriptrunner from 1 to 0.
}
