Trigger Commands
Triggers are functions which select if a trigger is triggered. For example, a trigger with “trig true” is always triggered, a trigger with “trig chance 25” has a 25% chance of being triggered.
trig Command Reference
trig bribe value
Returns true if trigger value is greater or equal then the given value. This is normally used in the bribe triggers.
trig chance percentage
A value between 0 and 99 will be rolled. If value is less then [Missing] this function returns True, otherwise False.
trig compare argnum text
Can be used for easy comparisons like:
- trig comp ==0 meaning [trig value]==0
- trig comp =="test" meaning [trig value]=="test"
- trig comp 0 =="test" meaning [trig value 0]=="test"
- trig comp <=26 meaning [trig value]<=26
- trig true Just returns true, to let triggers always be fired. (In the old mobprog system a chance of 100 percent was used)
Say in a pre-interpret trigger you want to check is the command used is ‘look’. use:
trig compare 0 ==“look”
proc squeek {} {
char echoaround Squeek squeek.
}
objtrigger 1 post_interpret { squeek } { trig compare 0 =="north" }
objtrigger 2 post_interpret { squeek } { trig compare 0 =="east" }
objtrigger 3 post_interpret { squeek } { trig compare 0 =="south" }
objtrigger 4 post_interpret { squeek } { trig compare 0 =="west" }
objtrigger 5 post_interpret { squeek } { trig compare 0 =="up" }
