Template:Wip Template:Infobox command
Evaluates Minecraft:number providers in various Minecraft:loot contexts.
Syntax
- Template:Cmd
- Template:Cmd
- Where Template:Cd is one of:
- Template:Cd
- Runs the provider with the [[Minecraft:Loot context#minecraft:command_compute_default|Template:Cd]] context, which provides common parameters such as the execution position and Template:Cd entity.
- Template:Cd
- Runs the provider with the [[Minecraft:Loot context#minecraft:command_compute_position|Template:Cd]] context, providing the block state and block entity found at Template:Cd alongside the common parameters.
- Template:Cd
- Runs the provider with the [[Minecraft:Loot context#minecraft:command_compute_entity|Template:Cd]] context, providing the selected entity as Template:Cd alongside the common parameters.
- Template:Cd
Float providers are evaluated to produce a floating-point value, but a command's Template:Cd value can only be an integer, so the actual result is rounded down to the nearest integer before being returned. If Template:Cd is specified, the result is multiplied by that before being rounded down, allowing more precision to be returned. Integer providers already produce an integer value, so no scaling is needed.
To store a float without losing any precision, see Template:Cmd instead, which avoids passing the value through Template:Cd.
Arguments
- Specifies the block whose state and block entity are made available to the number provider.
- Template:Arg desc
- Specifies the entity whose data is made available to the number provider as Template:Cd.
- Template:Arg desc
- Specifies the Minecraft:context float provider to evaluate. Can be an Minecraft:identifier or an inline definition.
- Template:Arg desc
- Specifies the Minecraft:context int provider to evaluate. Can be an Minecraft:identifier or an inline definition.
- Template:Arg desc
- Specifies the value by which the float provider's result is multiplied.
- If omitted, Template:Cd is used.
- The resulting value is rounded down to the nearest integer after scaling.
- Template:Arg desc
