I have once again trapped myself in quaternion hell

Caoimhe @sundry5/13/2024, 9:21 AM

Oh I just realised the the book I’m using defines y as the vertical axis but in SRB2 z is the vertical axis

Caoimhe @sundry5/13/2024, 1:12 PM

I have this working better now but I should probably fix this in a way that is not this

#gamedev #code gore

Caoimhe @sundry5/14/2024, 4:40 PM

Oh! That wan’t the problem at all! The way they book defined the axes didn’t conflict with they way I did it at all (I wrote all this code months ago and was coming back to it with hazy recollections). I literally just did the quaternion multiplication wrong for the step where I was accounting for the camera rotation.

not sure if I will continue with this but I have gotten some of the logic for animating a rolling character working

quaternion hell is the price of escape from the divine punishment of gimbal lock

3d is the original sin

Caoimhe @sundry5/13/2024, 5:00 AM

this is so true

echo wants to battle!@ysaie5/13/2024, 7:46 AM

ah yes, rotating and rotating, never to escape...

is that BLUE KNUX????

Caoimhe @sundry5/13/2024, 10:41 AM

I’m doing some mod development for Sonic Robo Blast 2. It lets you change characters’ colours for multiplayer games. A side effect of the want I’m launching the game for testing is setting the Knuckles to use the default colour scheme instead of his correct one.

I am now furiously googling to see if there is a SRB2 coldsteel mod

oh thats dire

Caoimhe @sundry5/13/2024, 6:56 PM

It’s also not actually fixed it turns out. I think that I do not have the mental energy to solve what I want to do here right now.

jayde @jayde5/13/2024, 6:57 PM

no one besides people who dont ship games (engine devs) can actually have the energy to make any sense of quaternions

Caoimhe @sundry5/13/2024, 7:07 PM

The purely quaternion stuff that is handling rotations is working fine actually the weird thing I am trying and failing to do is to translate the quaternion representations backs into Euler angles and then use those to try and figure out the animation state for the character sprite from it using an insane spreadsheet I was making.
