Projectile::onCollision

#1 Projectiles are designed to remove themselves after hitting something. You could record the transform of the projectile at the moment of impact and swap in a static shape (sames as your projectile shape) at the same orientaion/location.

#2 I think this would work perfect Michael. Would you know where I could see an example of what this part of the impact function would look like? Or able to give me the name of a book that goes over torque script in greater detail? (I've gone through All in one game programing editions 1 and 2 looking for more)

#3 Something like this as an example. This is untested ...

datablock StaticShapeData(DartShape)
{
   shapeFile = "art/shapes/crossbow/projectile.dts"; // change this to your shape and path
};

// DartProjectile is the datablock name of your projectile
function DartProjectile::onCollision(%this, %obj, %col, %fade, %pos, %normal)
{
   // do damage handling stuff here, if desired

   //  get the location and rotation of the projectile
   %trans = %obj.getTransform();
   
   // place a new shape at the location of impact using above %trans
   %dart = new StaticShape()
   {
      datablock = "DartShape";
   };
   %dart.setTransform(%trans);

   // make sure to add to MissionCleanup
   MissionCleanup.add(%dart);
}

#4 In regards to books to learn Torque script I can only suggest that any of them can help teach some script basics and concepts. The way I learned was by simply tearing into the scripts and figuring out how things worked. If I broke it then I learned by fixing it. Just start small with the easier concepts and build upwards, always learning.

#5 Thanks Michael, this works flawlessly, can not thank you enough for your assistance

#6 After some testing, it adds the model just as designed with out regard to the vector. So firing at say the side wall, it sticks but it sticks sideways.

Is their a better way to do it so it always faces the correct way, or do I need to play around with the transform a bit?

#7 Ooops, guess I should've tested that. The proper, although tricky, fix would be to do some vector math and storing a rotation matrix and simply adding that to the position when placing the new shape for a more accurate transform.

A quick and simple hack would be to get the player's rotation when you fire the dart, inside of your dartweaponimage::onFire()

%transform = %obj.getTransform();
$throwRot = getWord(%transform, 3) SPC getWord(%transform, 4) SPC getWord(%transform, 5) SPC getWord(%transform, 6);

And then inside of projectile::onCollision() change it so that the transform is concatenated from the %pos (the impact location) and the $throwRot (relative to the player's direction)

%trans = %pos SPC $throwRot;

This should make the static dart shape align with the direction it was thrown - though this doesn't account for vertical look direction.

#8 Works like a charm big thanks to you Michael. Would have taken me a very long time to figure all this out with out your help, learned a lot on this one.
