Experimental Features

Add-Ons and Script Engine​

  • Added "item_display_transforms" control to the block geometry file. This controls the way a block is visually represented in the UI, on the player, and floating on the ground. It exists inside the minecraft:geometry json object and requires geometry format_version 1.21.0 and the "Upcoming Creator Features" toggle
    • Default values example:
      • "item_display_transforms": { "gui" : { "translation": [0, 0, 0], "rotation": [30, 225, 0], "scale": [0.625, 0.625, 0.625], "rotation_pivot" : [0, 0, 0], "scale_pivot" : [0, 0, 0], "fit_to_frame" : true }, "firstperson_righthand": { "translation": [0, 0, 0], "rotation": [0, 45, 0], "scale": [0.4, 0.4, 0.4], "rotation_pivot" : [0, 0, 0], "scale_pivot" : [0, 0, 0] }, "firstperson_lefthand": { "translation": [0, 0, 0], "rotation": [0, -135, 0], "scale": [0.4, 0.4, 0.4], "rotation_pivot" : [0, 0, 0], "scale_pivot" : [0, 0, 0] }, "thirdperson_righthand": { "translation": [0, 2.5, 0], "rotation": [75, 45, 0], "scale": [0.375, 0.375, 0.375], "rotation_pivot" : [0, 0, 0], "scale_pivot" : [0, 0, 0] }, "thirdperson_lefthand": { "translation": [0, 2.5, 0], "rotation": [75, 45, 0], "scale": [0.375, 0.375, 0.375], "rotation_pivot" : [0, 0, 0], "scale_pivot" : [0, 0, 0] }, "ground": { "translation": [0, 3.0, 0], "rotation": [0, 0, 0], "scale": [0.25, 0.25, 0.25], "rotation_pivot" : [0, 0, 0], "scale_pivot" : [0, 0, 0] }, "fixed": { "translation": [0, 0, 0], "rotation": [0, 0, 0], "scale": [0.5, 0.5, 0.5], "rotation_pivot" : [0, 0, 0], "scale_pivot" : [0, 0, 0] }, "head": { "translation": [0, 0, 0], "rotation": [0, 0, 0], "scale": [1, 1, 1], "rotation_pivot" : [0, 0, 0], "scale_pivot" : [0, 0, 0] } }

Script API​

  • PlayerInteractWithBlockBeforeEvent
    • Added property readonly isFirstEvent: booleanto beta. This value will be true if the event was triggered on players initial interaction button press and false if triggered on holding the interaction button
  • PlayerInteractWithBlockAfterEvent
    • Added property readonly beforeItemStack?: ItemStack to beta. This is the item the player was selecting before the interaction succeeded
    • Added property readonly isFirstEvent: boolean to beta. This value will be true if the event was triggered on players initial interaction button press and false if triggered on holding the interaction button
    • This after event will no longer always trigger on an empty hand. The interaction with the block needs to be successful for it to trigger the after event
  • PlayerInteractWithEntityAfterEvent
    • Added property readonly beforeItemStack?: ItemStack to beta. This is the item the player was selecting before the interaction succeeded
    • Cancelling the before event will now no longer trigger the after event
    • This event will now only be triggered on a successful interaction

Graphical​

  • Fixed a variety of issues on the Mali device family of Android, most notably the "striped shadows" bug, in the Deferred Technical Preview (MCPE-175207)
  • Removed an incorrect offset when interpolating keyframe values for the sun illuminance and sun color. Keyframe values for sun illuminance and sun color are now consistent with other time-based keyframe values. Creators will need to shift any sun illuminance and color keyframes by 0.5. Documentation on the Creator portal has been updated accordingly
  • Added the ability to data-drive Sub Surface Scattering via Texture Sets in the Deferred Technical Preview. This effect allows light to penetrate the surface of objects up to a certain amount, similar to wax, leaves or skin. The default sub surface effect previously on leaves has been removed in favor of packs providing their own textures. Creators can use "metalness_emissive_roughness_subsurface"instead of "metalness_emissive_roughness" in their texture set JSONs to activate the effect on specific blocks, mobs, etc... Sub surface values are pulled from the alpha channel of the supplied texture. See updated documentation on the Creator portal for more information
    • Note that this new field is only available in texture set JSONs with a format version of "1.21.30"
  • Changed the color grading JSON schema for the Deferred Technical Preview to now require explicit enabling of highlight and shadow specific color grading settings. See updated documentation on the Creator portal for more information
  • Added highlight and shadow color grading controls to the Editor's Deferred Graphics Settings
  • Added the ability to data-drive emissive desaturation in the Deferred Technical Preview. See updated documentation on the Creator portal for more information
  • Added support for enchanted items in the Deferred Technical Preview
  • Reduced the smudging or “ghosting” artifacts that would occur when swinging the item in the player’s hand with Upscaling enabled in the Deferred Technical Preview
  • Fixed a variety of issues that caused certain objects to not cast shadows from point lights, and modified point light sources such that their geometry can no longer cast shadows in the Deferred Technical Preview
