I'm curious, does anyone know for a fact whether there's any difference between using boxes, or any other more spherical shape for triggers? From what I understand, LocationTriggers are always activated when an object enters their bounding volume, which is invariably cube-shaped. If that's true, it makes using any other shape for a LocationTrigger excessively tedious if you want a precise point at which the trigger is activated since you need to view the bounding volume in order to determine where the exactly the trigger will fire.
If so, why do we continue to use spheres for things like Ambient Sound? Surely cubes would make more sense? I guess it's just habit by this point.
Using triggers which aren't cubes?

Re: Using triggers which aren't cubes?
Nope. That's where you're wrong. Both Location triggers and Collision triggers can use the int BoundVol parameter to specify either a sphere or a cube.TheIdiot wrote:I'm curious, does anyone know for a fact whether there's any difference between using boxes, or any other more spherical shape for triggers?

Uh, because a sphere better determines the propagation of a sound from its point of origin? Alsooo, keep in mind that the default value is BoundVol isn't specified is 0, which corresponds to the sphere - for a cube, you MUST specify a value of 1.TheIdiot wrote: If that's true, it makes using any other shape for a LocationTrigger excessively tedious if you want a precise point at which the trigger is activated since you need to view the bounding volume in order to determine where the exactly the trigger will fire.

Re: Using triggers which aren't cubes?
machf is correct. Bounding Volume is sort of a tricky specification in Tres but, also quite straight-forward. All vertebrate embryos are inherently female, any--- I mean... All triggers are inherently spheres, anyway. You must both apply a BoundVol of 1 and a geometry type of 2, before the object in question is imported. Only then is a trigger a box-shape.
Don't sweat it - I've had a few of these details mixed in mind over the years. I used to think that Action## could only go up to 09, instead of 15, and this is reflected in trigger multiplicity in JPDS.
