Inconsistent Collisions?

by Jeremy Alessi · in Torque Game Engine · 02/21/2005 (4:19 pm) · 4 replies

I've changed a few things in my player.cs, crossbow.cs, and radiusdamage.cs files which have caused my explosions to only sometimes damage and push a player away. Often times the explosions do nothing ... what could cause this? The problem doesn't seem to be in radiusdamage.cs because when an explosion collision is registered it functions correctly. However, I can't seem to pinpoint by looking at the scripts that work (old ones) and the new ones what could cause this inconsistency. Any clues would be appreciated.

I've limited it to the crossbow.cs file ... I didn't realize but one of the .cs files wasn't compiling and so it was working of the old .dso file. Unfortunately ... I can't see what works right with that .dso file because even though I can make a compilable crossbow.cs file it doesn't function as it should.

Your best bet would be to post the script function(s) that don't work, and let us take a peek! Script is fine, just don't post any source code.

Yeah I fixed it ... but it's really strange ... here are the differences ...

// Doesn't work right
function CrossbowProjectile::onCollision(%this,%obj,%col,%fade,%pos,%normal)
{
   // Apply damage to the object all shape base objects
   
   if (%col.getType() & $TypeMasks::ShapeBaseObjectType)   
   {
      %col.damage(%obj,%pos,%this.directDamage,"CrossbowBolt");   
   }
   // Radius damage is a support scripts defined in radiusDamage.cs
   // Push the contact point away from the contact surface slightly
   // along the contact normal to derive the explosion center. -dbs
   
   radiusDamage(%obj,%pos,%this.damageRadius,%this.radiusDamage,"CrossbowBolt",%this.areaImpulse);
}

// Does Work
function CrossbowProjectile::onCollision(%this,%obj,%col,%fade,%pos,%normal)
{
   // Apply damage to the object all shape base objects
   if (%col.getType() & $TypeMasks::ShapeBaseObjectType)
      %col.damage(%obj,%pos,%this.directDamage,"CrossbowBolt");

   // Radius damage is a support scripts defined in radiusDamage.cs
   // Push the contact point away from the contact surface slightly
   // along the contact normal to derive the explosion center. -dbs
   radiusDamage
     (%obj, VectorAdd(%pos, VectorScale(%normal, 0.01)),
      %this.damageRadius,%this.radiusDamage,"Radius",40);
}

Not sure if it's that hardcoded 40 but that doesn't seem like it should be the problem because otherwise it would never work if it were getting a 0 or something ....

Two possible things:

1) Your %this.areaImpulse had a value of 0 possibly--which would mean no actual radius to act upon?
2) You also changed the next to last parameter from "CrossbowBolt" to "Radius"--again, not sure what the actual parameter is supposed to be, but could be possible this was the issue?
