GM: Step

From GMpedia.org Wiki

This article is about the concept of a step in Game Maker, for the Game Maker event, see GM: Step Event

A step (informally a millisecond) is a unit of time in Game Maker. It has no constant magnitude, but instead depends on the settings of the user which define the length of a single step in the game. Each room can have its own step-length (depending on theRoom Speed). As the room speed increases, the step-length decreases.
