Note: This page describes a unit used in Okami. To learn more about the values representing quantities of these units, see Reverse Engineering.

Explanation

A Frame is the minimum progression of time in-game. Inputs are polled, the game state is updated, and the image displayed on-screen once per frame. During normal gameplay, Okami generally runs at a fixed frame rate of 30 frames per second (FPS). In some menus, such as the pause and fan menus, the game instead runs at 60 FPS.

Mechanics

  • Many constants and values in-game are also represented in terms of a rate of change per-frame. For example:
    • Health lost to being on fire, or health gained via the Wood Mat.
    • Ink consumed while drawing on the canvas, or ink recovered over time during normal gameplay.
  • Whether the game is running at 30 FPS (general gameplay) or 60 FPS (some menus) is determined by the 1 byte Framerate Divisor value located at main.dll+B6AC45.
    • It is set to 1 in menus, and 2 in general gameplay.
    • Using tools to change it to 1 during gameplay causes the game to run at 60 FPS, but causes physics and various game mechanics to behave strangely.
