Position Behind a vehicle
Brian Smithers:
How do I get the position behind a vehicle?
Help appreciated!
Destiny/Zack0Wack0:
--- Code: ---function getObjectBackPosition(%obj) {
%box = %obj.getWorldBox();
%max = getWords(%box, 3, 6);
%min = getWords(%box, 0, 2);
%size = vectorSub(%max, %min);
%sizeX = getWord(%size, 0);
%sizeY = getWord(%size, 1);
%sizeZ = getWord(%size, 2);
%forward = %obj.getForwardVector();
%scaleX = getWord(%forward, 0) * 0.5;
%scaleY = getWord(%forward, 1) * 0.5;
%scaleZ = getWord(%forward, 2) * 0.5;
return vectorSub(getWords(%obj.getTransform(), 0, 2), %sizeX * %scaleX SPC %sizeY * %scaleY SPC %sizeZ * %scaleZ);
}
--- End code ---
I may be overcomplicating it, but it works.
Xalos:
getWorldBox isn't 1-to-1 scale, I know from experience.
Plus "behind" would be relative to the vehicle, so you should use getEyeVector instead of getForwardVector.

doesn't getForwardVector() return the front of the collision box?

getForwardVector() returns the normalized vector that the object is facing. It has nothing to do with positions.
