EasyShade contains functions for automating the lighting of Aleph One levels. It is intended to aid mapmakers in conjunction with their usual lighting techniques. EasyShade currently includes these functions (all parameters are optional):

sunlight(contrast, manual\_sun\_angle, cumulative) for simulating a directional light source that affects all surfaces and does not cast shadows

roomlight(brightness, floor\_threshold, ceiling\_threshold, radius) for assigning a brightness to an entire room at once

pointlight(brightness, max\_radius) for simulating a point light source where the player is standing (calculations done in 2D)

darken() and lighten() for nudging the brightness of the room you're in up or down. These functions are tied to the previous and next weapon keys, so you can make an adjustment by pressing one key instead of typing out a function call.

pavelight(brightness) for applying a single brightness to all surfaces in the entire level

resetlights() for restoring a level to its original lighting levels

Major update, now with wholly different types of automated lighting.
