How a trigger work?
A trigger work spawning the model , moving up and playing sounds.
Triggers are used for : 'moving objects', they are used to 'trigger' another entity,prefab,texture and xmodel to 'interact, spawn or hide' when walked though or activate.
So if you want to do something like a bounce betty you will need to do something lioke this:
That code will move up the model you want to move
stepOnBetty = spawn( "trigger_radius", betty.origin, 1, 20, 10 );
stepOnBetty waittill( "trigger", i );
betty MoveTo(betty.origin +(0,0,70),0.4);
So i hope you enjoy ,
Thanks for reading.
