+# player_physics
+A minetest mod to centralize the management of player's stats(sprint, jump, gravity)
+Because many mods (sprint, 3d_armor and others) rewrite the stats in their corner and it cancel
+
+
+***API***
+
+ - player_physics.set_stats(player, "uniq_name", table)
+
+ - player_physics.remove_stats(player, "uniq_name")
+
+**Exemple**
+ 
+ - player_physics.set_stats(player, "potion_speedlvl1", {speed=0.35})
+ 
+ - player_physics.set_stats(player, "sprint_mod", {speed=0.35, jump=0.1})
+ 
+ - player_physics.remove_stats(player, "potion_speedlvl1")
+
+**Temporary effect**
+
+ - player_physics.add_effect(player, "uniq_name", time, stats)

+You make a potion that adds speed for 10 seconds.
+
+    on_use = function(itemstack, user, pointed_thing)

+       itemstack:take_item()
