Player Status Uniforms

These uniforms store information about the status of the player in the world, including gamemode, potion/status effects, current health/hunger/etc, user options related to the player, and more.

isEyeInWater

uniform int isEyeInWater;

This uniform outputs the current substance that the camera is in. Possible values are:

value	state
`0`	none/other
`1`	water

isSpectator Iris Exclusive

uniform bool isSpectator;

This value is true when the player is in spectator mode and false otherwise.

isRightHanded Iris Exclusive

uniform bool isRightHanded;

This boolean uniform is true when the player is using the right hand (default) as the main hand and false when the left hand is set as the main hand through the Minecraft settings.

blindness

uniform float blindness;

This value stores the blindness effect as a multiplier. It ranges from 0 to 1 where 0 is no blindness and 1 is full blindness. The uniform is only between 0 and 1 during transitions between having or not having blindness. More information on the blindness effect can be found at the Minecraft Wiki.

darknessFactor

uniform float darknessFactor;

This uniform stores the strength of the darkness effect. The value is 0.0 when the effect is not present, 1.0 when the effect is active, and is interpolated between those values during transitions.

darknessLightFactor

uniform float darknessLightFactor;

The darkness status effect creates a pulsating dimming effect in the game lighting. This uniform stores the current strength of the dimming effect. The value is 0.0 is the minimum dimming, 1.0 when the effect is the maximum dimming, and is interpolated between those values during transitions.

nightVision

uniform float nightVision;

This value stores the night vision effect as a multiplier. It ranges from 0 to 1 where 0 is no night vision and 1 is full night vision. The uniform is only between 0 and 1 during transitions between having or not having night vision. More information on the blindness effect can be found at the Minecraft Wiki.

playerMood

uniform float playerMood;

This uniform stores the player’s mood value. This value increments when the player is in a cave (or any structure with low block and sky light). The value ranges between 0.0 and 1.0 and resets to 0.0 after it increments to 1.0. More information on mood can be found at the Minecraft Wiki.

constantMood Iris Exclusive

uniform float constantMood;

Equivalent to playerMood except when it does not reset after hitting 1.0, remaining at that value until the player leaves a cave or otherwise causes the mood value to decrease.

currentPlayerAir Iris Exclusive

uniform float currentPlayerAir;

This value stores the relative player air when underwater ranging from 0 to 1. That means when the player is at full air, this value is 1, and when they are out of air (e.g. drowning) the value is 0. The value is -1 in creative and spectator modes. To absolute air of the player, multiply this value by the uniform maxPlayerAir.

maxPlayerAir Iris Exclusive

uniform float maxPlayerAir;

This value stores the maximum player air when underwater. This is the internal value used by Minecraft, not the number of bubbles in the user interface. This value is -1 in creative and spectator modes. In a default survival world this value is 300.

currentPlayerArmor Iris Exclusive

uniform float currentPlayerArmor;

This value stores the relative player armor value ranging from 0 to 1. That means when the player wearing armor that completely fills the armor bar this value is 1, and when they are not wearing any armor the value is 0. The value is -1 in creative and spectator modes. To absolute armor value of the player, multiply this value by the uniform maxPlayerArmor.

maxPlayerArmor Iris Exclusive

uniform float maxPlayerArmor;

This value stores the maximum player armor value. This is the internal value used by Minecraft, not the number of armor icons in the user interface. In a default world this value is 50 unless changed by mods. Modes without hunger (such as creative and spectator modes) will still indicate the same maximum armor value.

currentPlayerHealth Iris Exclusive

uniform float currentPlayerHealth;

This value stores the relative player health ranging from 0 to 1. That means when the player is at full health, this value is 1, and when they die this values reaches 0. The value is -1 in creative and spectator modes. To absolute health of the player, multiply this value by the uniform maxPlayerHealth.

maxPlayerHealth Iris Exclusive

uniform float maxPlayerHealth;

This value stores the maximum player health value, which is twice the number of maximum hearts (one value for each half-heart). The value is -1 in creative and spectator modes. In a default survival world this value is 20 unless changed by mods or effects like Health Boost, in which case the maximum value can be up to 1024. This value is not affected by the Absorption effect, such as with golden apples.

currentPlayerHunger Iris Exclusive

uniform float currentPlayerHunger;

This value stores the relative player hunger ranging from 0 to 1. That means when the player is at full hunger, this value is 1, and when they are at empty hunger the value is 0. The value is -1 in creative and spectator modes. To absolute hunger of the player, multiply this value by the uniform maxPlayerHunger.

maxPlayerHunger Iris Exclusive

uniform float maxPlayerHunger;

This value stores the maximum player hunger value, which is twice the number of hunger icons in the user interface (one value for each half-hunger icon). In a default survival world this value is 20 unless changed by mods. Modes without hunger (such as creative and spectator modes) will still indicate the same maximum hunger value.
