Block Documentation - minecraft:flammable

minecraft:flammable is a Boolean or JSON Object component that describes the flammable properties for this block. If set to true, default values are used. If set to false, or if this component is omitted, the block will not be able to catch on fire naturally from neighbors, but it can still be directly ignited.

Default Value of the Component

This component can be specified as a Boolean. If this component is omitted, the default value for this component is false (the block will not be able to catch on fire naturally from neighbors, but it can still be directly ignited).

Parameters

minecraft:flammable can use the following parameters:

Name	Default Value	Type	Description
catch_chance_modifier	5	Integer	A modifier affecting the chance that this block will catch flame when next to a fire. Values are greater than or equal to 0, with a higher number meaning more likely to catch on fire. For a catch_chance_modifier greater than 0, the fire will continue to burn until the block is destroyed (or it will burn forever if the "destroy_chance_modifier" is 0). If the catch_chance_modifier is 0, and the block is directly ignited, the fire will eventually burn out without destroying the block (or it will have a chance to be destroyed if destroy_chance_modifier is greater than 0). The default value of 5 is the same as that of Planks.
destroy_chance_modifier	20	Integer	A modifier affecting the chance that this block will be destroyed by flames when on fire. Values are greater than or equal to 0, with a higher number meaning more likely to be destroyed by fire. For a destroy_chance_modifier of 0, the block will never be destroyed by fire, and the fire will burn forever if the catch_chance_modifier is greater than 0. The default value of 20 is the same as that of Planks.
