Not much nonsense, directly on the code.

 // Use formula examples

Deploying (
, // Items used = inputItem
"Minecraft: Grass", // The converted block = inputBlock type string
0, // Meta value of the converted block = inputBlock_Meta (not filled 0)
, //
2, // Meta value converted into the block = inputBlock_Meta (not filled 0)
True // Whether it consumes items used = itemexpended settings to true and consume
// Use the wooden stick (consumption) to convert the grass square into a birch board
Cure
// Image high -version mechanical power "use" formula function
Function Deploying (INPUTITEM As IITEMSTACK, InputBlock as String, InputBlock_Meta as Int, OutputBlock as IITEMSTACK, OUTPUTBLOCK_META AS Int, Itemexpend as Bool) {
Events.onPlayerInteractBlock (Function (event as playerInteractBlock) {{
Var deploying_block = event.block;
Var deploying_item = event.item;
Var deploying_position = event.position;
Var World0 = EVENT.WORLD;
Var Player = Event.player;
If (inputITEM.Matches (deploying_item)) {{
If (! Isnull (deploying_block) && deploying_block.definition.id == inputBlock &&BLOCK.Meta == InputBlock_Meta) { World0.Destroyblock (deploying_position, false);
World0.SetBlockState (OutputBlock.asblock (). Definition.getStateFrommeta (outputBlock_meta), deploy_position)
Event.player.sendstatusMessage (format.red ("" §4 successful! ");
IfMexpend! = False) {
Deploying_item.mutable (). Withamount (deploying_item.amount-1);
}
}
}
});
}

If you want it, take the Copy for free and use love to generate electricity (after all, it is a very simple event to complete)

(I am also a hard -working incident, just do not provide a principle tutorial!)
