Falling into walls in original PoP

[David]

atrueprincefanfrom18 sent me this in a PM:

Hello, I was playing the original PoP1 Level 2 and I did something odd and this thing happened... Why would it had happened? Please will you check the attached p1r files and let me know?

This is a glitch in the game, and it's a glitch which I haven't seen yet.
Nice find!

I could reproduce it in the original (DOS) PoP as well, so this glitch is not specific to SDLPoP.
(SDLPoP is based on the DOS game, so it "inherited" the bug.)

To reproduce it in the DOS version:
If I simply climb up to that ledge, the prince will already be aligned as needed for this glitch.
Although in the DOS version, the prince will end up in a different room.

Yes, sure, please put it for others to view, have absolutely no problems.
I don't exactly know where it would properly fit in, that's why I sent you a private message.
But the main question still remains... I played again and some elements changed. Where is the room where the kid lands? At what other places can this happen and why?

If you press C in cheat mode then you'll see that this strange room is room 128 in SDLPoP and room -128 in DOS PoP.
This is an invalid room number, which means the game will read some out-of-range memory area as if it was level data.
That area doesn't contain any valid level data, so its contents will appear as a garbled room.

A similar glitch can happen if the prince dies at a place where there is a wall immediately on his right, and you revive him with R (in cheat mode).
The prince will fall into the wall, and he'll end up in a glitched room like in your recording.
Here is an example: https://youtu.be/-oEJBESyTVs?t=121

I think the same glitch happens here at 1:57.

Is it the same bug as this video, maybe ?

Yes, it's a trick discovered already. Trick 95.

It's also possible on left side, but you need to get proper distance to replicate the same:

This one is where you can go through the tile:

This one is a fall, so you land with a loss of one HP. But you can go through

I have used this trick in some of my mods previously. Maybe you can try some!

hi all,

I was not able to replicate this, and I don't know how well-known this is, but in Level 10 if I make a standing jump from here

I end up here:

EDIT: It can be replicated as follows. From the edge of the short platform on the right, do 1 standing jump, 4 quiet steps, turn right, do the "climb up" jump, turn left, standing jump.

Nice find!

I tried what you wrote, but in my case the prince fell into an empty room and then landed in an actual room of the level.
And somehow the purple guard in that last room became orange. Weird.

By the way, a similar glitch was found on level 2: viewtopic.php?p=27589#p27589

Interesting!

Btw I notice that in David's attachment the last guard indeed became orange, but Norbert's video it did not

Cool! I guess it's time to try to go through all walls of original PoP!

Would be great if you merge this topic to that one and rename that topic to "Going through walls in original PoP" or something like that.

And on the console:

Code: Select all

Tried to use frame_tbl_guard[-149], not in 0..40

I was playing on SDLPoP, not DOSBox.

Err. Then David must have replaced his attachment... I guess.

I downloaded it now and didn't see any orange guard... Weird.

Wait!
In VLC Media Player it's Orange and in normal Videos Player it's Purple. I am using Ubuntu and I don't know the name for default Videos Player. Something is very weird...

David, how did you create the video?
