Alternative to getEyeVector(); that ignores freelooking?

[Crystalwarrior]

Alright, so I have this function here by port.

Code: [Select]

function Player::getLOSPoint(%this, %mask, %dist)
{
%eyePoint = %this.getEyePoint();
%eyeVector = %this.getEyeVector();
%endPoint = vectorAdd(%eyePoint, vectorScale(%eyeVector, %dist));
%ray = containerRayCast(%eyePoint, %endPoint, %mask, %this);

if (%ray)
{
return getWords(%ray, 1, 3);
}

return %endPoint;
}
It works just dandy, but the problem is that getEyeVector(); takes freelooking into account as well, so if I use this for weapons I could just hold freelook and fire backwards.
Is there any alternative to getEyeVector(); that ignores freelook?
By the way, before you ask, I did try getWords(getForwardVector(), 0, 1) SPC getWord(getEyeVector(), 2); but for some dumb ass reason getForwardVector can't go below or above a certain angle.

Well, you could probably do something like this:

Code: [Select]

%vector = getWords(%player.getForwardVector(),0,1) SPC getWord(%player.getEyeVector(),2);

That SHOULD get you the x/y of forwardVector (direction they are facing regardless of freelook) and the Z of their eye (which is unaffected by freelook)

[$trinick]

Above and below are relative terms of Z axis, and we're grabbing only the X and Y axis from getForwardVector. I don't understand what you're trying to say.

[$trinick]

Anyway, to more directly answer your question: getMuzzleVector(0) works.

[Crystalwarrior]

Well, I should probably post the code snipped I have in my WeaponImage::OnFire.
Maybe that'll help figure out why does the angle snap happen.

Code: [Select]

%losPoint = %obj.getLOSPoint(%mask, %this.raycastRange);

%basePoint = %obj.getMuzzlePoint(%slot);
%baseVector = vectorNormalize(vectorSub(%losPoint, %basePoint));

[Port]

That code is irrelevant, it's just the ::getLOSPoint from my raycasting weapons that actually matters in this case.

[$trinick]

Again, Player::getMuzzleVector( 0 ) works just fine for getting where somebody is looking minus freelook. Does it still snap when you use that?

[Swollow]

isn't getMuzzleVector affected by the weapon your holding and takes the weapon bobbing into factor?

[$trinick]

Well, first off it appears that he's making a custom weapon so he could just make it so there's no muzzle offset. And no, the muzzle point is affected by weapon bobbing. But secondly, calling getMuzzlePoint on a slot that doesn't have a weapon on it produces the same exact result as getEyeVector when freelook is not being used.

[Port]

Using it for ::getLOSPoint would pretty much be beside the point since it would just fire along the muzzle vector always.

[$trinick]

His version of getLOSPoint appears to use getEyeVector instead of getMuzzleVector.

[Port]

Currently, his issue is trying to get ::getForwardVector() with Z rotation included.
Just changing the third word doesn't work, as it adds them (i.e. looking straight up would give a diagonal such as 0 1 1).

[Crystalwarrior]

So Port came up with this code, but the problem is that Z is kind of inaccurate. When you look diagonally up, it doesn't shoot directly at the cursor but instead slightly above or something.

Code: [Select]

function Player::getLOSPoint(%this, %mask, %dist)
{
%start = %this.getEyePoint();
%forward = %this.getForwardVector();
 
%z = getWord(%this.getEyeVector(), 2);
 
%xyScale = 1 - mAbs(%z);
%xyScale = mSin(%xyScale * ($pi / 2));
 
%vector = vectorScale(%forward, %xyScale);
%vector = setWord(%vector, 2, %z);
 
%end = vectorAdd(%start, vectorScale(%vector, %dist));
%ray = containerRayCast(%start, %end, %mask, %this);
 
if (%ray)
{
return getWords(%ray, 1, 3);
}
 
return %end;
}

[Port]

Before anyone mentions that: Tried without a mSin scale too.
