Saints Row 3 and 4 Zone File Tools

[Quantum]

Hi, what this data means? I was thinking that some rotation parameter but it also change the scale of the object.

                    <orientation>
                      <x>0,001</x>
                      <y>0,929238617420197</y>
                      <z>0</z>
                      <w>0,369480282068253</w>
                    </orientation>

This represents a quaternion.

I believe this represents a quaternion, but I'm not 100% sure. It may also represent a homogenious coordinate, but, since it's defined as an orientation, I would think it should be a quaternion. I haven't actually experimented enough with these myself to give you a definitive answer.

Okay, that makes sense but rotating objects now become not so trivial thing as I thought

I updated my previous post. It's definitely a quaternion.

So the ratio between (x,y,z)/w should be always the same? And if not model will look distorted? Jeez I forget about math and matrixes long ago

Ha ha ha! Who thought this stuff would actually be useful?

Yeah, you need it to rotate object in the game where programmers choose fast code, not usability
Okay Google say me that w = cos(rotation angle /2) and x, y, z =rotation vector*sin(rotation angle /2) but what units used here? I saw some value around 9, so xsqr+ysqr+zsqr+wsqr isn't = 1

Radians? I know Volition uses some strange non-standard units for rotation sometimes.

Yeah this should be radians. Jeez, when you rotating objects in Saints row.

But looks like it works, I found that original angle was 136 degrees and replace it with 30. But this thing should be automated

If there's anything I can do to help, let me know. I stopped working on the zone file tools because nobody seemed to be using them (except myself, for my own mods). I was frustrated that I couldn't add or delete items without crashing the game. Knobby was helping me, but he was very busy and now he's no-longer at Volition.

This is very sad. This tool has potential to be level editor but without Volition help it hardly possible
