(I've just been getting into speedrunning OoT3D and am new to the forums, so please tell me if I do/have done something wrong, which I'm sure I'll do. I didn't know whether to start a new thread for this or not, but I figured not doing it was best.)
So I don't really know if this has already been discussed and/or is already known, but I've been looking into finding a warpless DoT skip for OoT3D and have found some things about the actual door itself. First, the door isn't actually thick the whole way through. It's only thick in the center of the door (I'm assuming this is because it's just enough to make the door look thick during the cutscene where it opens). If you position Link against the door and L-target, you'll see that at the sides of the door, it's actually very thin, almost like a texture but with collision. I know that the door now extends into OoB, so N64 DoT skip is highly unlikely (pretty much impossible), but since it was so thin I wondering if a clip was possible. I tried messing around in the corner, and found that there is a specific angle where Link's sword (just to make sure, this is child Link I'm talking about) can hit the walls, allowing for a TSC. I doubt a regular TSC would work, but I tried something similar to the TSC void warp at ganon's castle by using RI to place a bomb and then RI again to pull another one for the tsc. I hadn't really practiced the trick, so not much came of it, but I hope to look into it more. Also, I noticed that the little lip in the wall perpendicular to the door makes the space there a lot smaller, I tried HESS'ing off a bomb (placed with RI) into the corner and when I did that, Link spazzed out and was moving back and forth rapidly, half-clipping into the door and stuck in the corner. I thought about side hopping or rolling on a frame where Link was half clipped, but, unfortunately, I was short on time, so I couldn't do too much more experimenting. If anyone also wants to look into this, it would be much appreciated. I though this would be useful in No RBA/WW runs as it would skip the spiritual stones. Once again, I am new to the forums so I apologize if I am going about this wrong or if I don't know enough about this game to see flaws in my ideas (of which I'm sure there are).
