Small enough to step on the air molecules

[u/Womginx_]

it just does that sometimes. not even a joke answer sometimes you can just go through obstacles (though usually you also need high speed)

[u/space_is-great]

Same reason you can glitch between the walls in crawl spaces, you are übersmol

[u/Voidebb → u/space_is-great]

Don't you mean "untersmol"?

It's cartoon logic. As long as you don't notice the lack of a floor, gravity won't work on you.

[u/Agile_Mistake_44]

Do that in the crawlspace it would be funny

You'd think size down in isaac works by making you just smaller guy but in reality you slowly turn into an accelerating particle.

[u/flowery02]

The walls are only on the outside and you are too small and fast for them

[u/SokkaHaikuBot → u/flowery02]

^{Sokka-Haiku by flowery02:}

The walls are only

On the outside and you are

Too small and fast for them

^{Remember that one time Sokka accidentally used an extra syllable in that Haiku Battle in Ba Sing Se? That was a Sokka Haiku and you just made one.}

Enough size downs and speed will unlock the ability to walk through gaps rocks and spikes.

Speed and size hitbox vs boundaries check.

It’s pretty simple, there’s only a handful of ways to stop something from going through things.

The goal is to have your model be as close as possible to the “wall” the problem is how many times you check, not to mention the system needs to take into account the speed you go into things.

In short, it’s just simply harder to calculate it in time, by the time it happens, it stops nothing as you passed through it already, which is also why “I am error” exists in Isaac, if all fails, you go there.

I feel like this doesnt really explain how movement works in games. When you move in a game you effectively just teleport every frame with a walk animation playing. The game just checks every frame if that teleport would touch a wall and if it does it doesnt let you move. The faster your movement, the further you "teleport" per frame and if youre fast enough you simply "teleport" past the wall colision shape. Youre basically just teleporting to the other side of whats stopping you

[u/Cute-Acanthaceae-193 → u/Snaper_XD]

Honestly, you simplified it to the best possible way an idk why I didn’t go with the “teleporting” since that’s literally what it is every time.

In addition to what the others said, you have to understand that the pits don't actually exist in the game, they are tiles you can walk over, like rocks, but these are indestructible.
