Really Interesting Rendering Bug

[Onar4241]

Actually, I'm not sure if this is a bug or my mind is driving crazy. I recently decided to revisit ZDoom and play a few mods with it, and started playing Real Guns Hardcore on it (Where weapons literally kick like a mule). While I blowed the fuck out of the hellspawn, I decided to do something weird. The ZDoom wiki says that true look up and down in ZDoom is not possible because it would make ZDoom having infinite number of lines to render, so it is technically impossible. Well it seems like this mod's weapons actually break the limits. I was able to look even more upward than ZDoom allows me to. I fired multiple shots with the M249 SAW, which has crazy recoil and screen shake and I happened to pass the limit and when I stopped, I could still see how the renderer screwed up. You have literally never saw that stretched and badly rendered pixels in a game. At one point, it seems that I literally break the limits, but ZDoom forced me to look all the way down. From what I understand ZDoom forces me to look all the way down when I try to pass the limits (Possible to prevent a crash) and forces my view to that angle for the same reason. I did it 3 times before my computer happened to freeze for 1 second and crashed with a sadden blue of screen of death and restarted.

Still, that was a really interesting experiment!

Haha.
Are you sure you're using the latest version? There was a problem with A_SetPitch a long time ago (I believe) where it didn't clamp the pitch between -90 and 90. (Maybe it still exists in the ACS functions?)
If you were playing in OpenGL, you would have the camera upside down and looking at the opposite angle it's supposed to be at instead of it just instantly pointing downwards. (I believe it would stay pointing straight up in software until the pitch reached -90, where it would instantly point downwards)

I have the latest development build, and I actually find the bug pretty damn amazing!

Seeing as ZDoom is a user program, not a kernel driver, you may want to begin checking your hardware/drivers for defects (instead of posting overtly long and difficult to read bug reports).

Please post something comprehensible. I have no desire trying to decipher that blurb.

He's claiming to have had a view pitch beyond ZDoom's limits, caused by the weapon coding in Real Guns Hardcore.

It is not the only mod that does that, it's in general weapons that have lots of kick and recoil.

[Onar4241]

Why is this marked as useless? Because I'm afraid I made no sense, here are some screenshots.

You can't get higher view than that.

After firing a few shots I break that limit

I LITERALLY break the limit

See how this is not useless, but actually something really interesting?

A link to the wad would help.

[Graf Zahl]

It was marked as useless because your initial description was incomprehensible for analysis.

[Raziel236]

Just like an initial topic tag is useless.

So that's what it looks like unclamped in the software renderer... :O That's hilarious TBH.

[Edward-san]

If you coop-spy a zcajun bot while fighting against a flying monster, you can see the same thing, more or less

[Onar4241]

So I guess with the pictures above, free look IS possible in ZDoom, but it will look washed out. Maybe that's what Randy tried to avoid.

I had to close my computer for 3 days, that's why that happened.
