These are theoretical values, and in reality less resistant blocks are not always destroyed there is no such mechanic.ĭestroyed blocks have a 1⁄ p chance of dropping as collectible resources, where p is the explosion power.
Thus, the block resistances are 24.2 (charged creepers), 15.534 ( TNT), 11.2 ( creepers), 3.284 ( fireballs).TNT and creeper explosions are always 0.49 and 0.5 blocks away from nearest block (2 attenuation steps), but fireball explosions can happen anywhere (1 attenuation step). For explosion in air, there is at least one attenuation step. The attenuation steps is subject to collision restrictions.To not be destroyed, a block has to absorb all blast force at the first checkpoint in it. The minimum block resistance required to absorb maximum blast force of an explosion happening in nearby air = ((1.3 × power − attenuation steps × step length × 0.75)/ step length − 0.3).However, how many blocks an explosion can destroy is non-deterministic and also dependent on the specific location of the explosion. For example, a TNT explosion can destroy a torch 7 blocks away. The maximum blast radius (assuming no block absorption) is = 10.4 ( charged creepers), 6.9 ( TNT), 5.2 ( creepers), 1.7 ( fireballs).The ray destroys any blocks that could not reduce the ray intensity to zero at any checkpoint.įrom the above process, the following results can be deduced (where is the floor function):.If the block passed through is anything other than air, it is further reduced by ( blast resistance + 0.3) × 0.3. For every attenuation step (0.3 blocks along the ray), the intensity of the ray is reduced by 0.225 (0.3×0.75).Each ray is given an intensity, calculated as (0.7 + ) ×.A cube around the explosion is divided into a 16×16×16 grid, and rays are created from the center to each outer point of this grid, meaning that there are a total of 1352 rays.Its blast effect is evaluated independently on many explosion rays originating from the explosion center, as shown in the right figure.Īn explosion must be powerful (power ~1542860 ) to destroy a bedrock block. The roughly spherical pattern of blocks destroyed can be seen here.Īn explosion can destroy nearby blocks. (However, this defines only their directions, not their length). The rays from the explosion center to points that are uniformly distributed on the surface of a cube centered at the explosion with an edge length of 2. Lab tables sometimes perform a non-terrain-damaging explosion when creating garbage item. Ĭomparison of explosion craters, from charged creeper (left), TNT (center) and creeper (right). Does no terrain damage when the mobGriefing game rule is set to false.ĭespite doing damage to entities, fireworks do not destroy terrain and as such are not counted as conventional explosions.Ĭauldrons perform a non-terrain-damaging explosion when incompatible liquids are mixed. Treats blocks within blast radius (except bedrock, end portal, end gateway, end portal frame, command block, structure block, structure void and barrier) as having a blast resistance of no more than 0.8. Does no terrain damage when the mobGriefing game rule is set to false. Respawn Anchor when used in the Overworld, the End or custom dimensionsĪny blocks destroyed by explosion drop their respective items.
