Glide

In Doom speedrunning, a glide is a movement through a space which is typically 32 units, in which the players' position relative to the space has no fractional component, and is facing in the direction of one of the axes. Various methods exist for executing glides

Categories
A guided, or "right angle" glide is a glide in which there is a wall protruding on one of the edges of the space (e.g. doom2 map16). In order for the glide to succeed, the player must simply get his angle aligned with one of the axes and use forward mouse sensitivity to push himself through.

A flat faced glide is one in which both edges of the glide are flat, and the player must align himself both angularly, and positionally (e.g. doom2 map02). This variety is rarely done in non tool-assisted speedruns due to the fact that such glides often have monsters in close proximity which can ruin the players' attempts at positioning.
