+# POVA
+
+Pova gives mod makers a set of easy to use functions that safely apply overrides for player speed, jump height and gravity effects.
+
+## Settings
+
+'pova_loop' setting is 1.0 by default and will calculate and set overrides once a second for each player, set to 0.5 for every half a second or 0 to disable.
+
+## Functions
+
+pova.add_override = function(name, item, def)
+
+- Adds a named override which can be used to add or subtract from speed, jump and gravity effects.  Custom overrides are also used for specific tasks:
+
+- "default" sets default values for each of the settings to which overrides are added.
+- "min" provides a minimum level for each of the settings.
+- "max" provides a maximum level for each of the settings.
+- "force" overrides all and forces a value for each setting (e.g setting speed to 0 when sleeping in beds)
+
+ - 'def.priority' can be used to set priorities for custom effects, higher numbers get applied (defaults to 50)
+
+pova.get_override = function(name, item)
+
+- Returns the table containing {speed, jump, gravity} for an added item.
+
+pova.del_override = function(name, item)
+
+- Removes the override settings for the item named.
+
+pova.do_override(player)
+
+- Calculates and sets new overrides instantly, this can be used when the 'pova_loop' setting is false.
+
+
+## Changelog
+
+### 0.1
+
+ - Initial Upload
+
+### 0.2
+
+ - Added pova.do_override(player) to instantly set overrides on list.
+ - Added 'pova_loop' setting in minetest.conf to disable override calc loop
+
+### 0.3
+
+ - Added custom override names for special functions "default", "min", "max", "force"
+ - Tweaked test axe to use new settings.
+
+### 0.4
+
+ - 'pova_loop' now contains loop timer in seconds, 0 to disable
+ - Added def.priority setting to add_override to stop unimportant changes
+ - tweak and optimize code
