[1.20.1] [SOLVED] Checking if a block has a property

[A tired guy]

Say if I want to check if a block has an AGE property, how would that be done with any block?
Not an AGE property of a singular block. Specifically if a block even has such a property.

BlockState has a .hasProperty() method, so I'd imagine this would work

public boolean blockHasAge(BlockState blockState) {
    return blockState.hasProperty(MyModBlockProperties.AGE);
}

This will only work on that specific block's property.

Hm not sure what you're asking for then. Can you give a pseudocode example or explain differently what your intention is here?

As I said in the first message, I want to check if a block even has such type of a property

nvm found a solution

if(state.getBlock() instanceof BushBlock )

{

 

}

may you are talking about catching all the AGE declaration even the ones from other mods custom properties ?

one would be to check only againts the minecraft BlockStateProperties class

  Reveal hidden contents

				
			import net.minecraft.world.level.block.state.properties.BlockStateProperties;				
			// ########## ########## ########## ##########
		public int get_AGE() {
		if (this.level > -1) {
		return this.level;
		}
		
		BlockState blkstate = this.getBlockState();
		
		if (blkstate.hasProperty(BlockStateProperties.AGE_1)) {
		return blkstate.getValue(BlockStateProperties.AGE_1);
		}
		
		if (blkstate.hasProperty(BlockStateProperties.AGE_2)) {
		return blkstate.getValue(BlockStateProperties.AGE_2);
		}
		
		if (blkstate.hasProperty(BlockStateProperties.AGE_3)) {
		return blkstate.getValue(BlockStateProperties.AGE_3);
		}
		
		if (blkstate.hasProperty(BlockStateProperties.AGE_4)) {
		return blkstate.getValue(BlockStateProperties.AGE_4);
		}
		
		if (blkstate.hasProperty(BlockStateProperties.AGE_5)) {
		return blkstate.getValue(BlockStateProperties.AGE_5);
		}
		
		if (blkstate.hasProperty(BlockStateProperties.AGE_7)) {
		return blkstate.getValue(BlockStateProperties.AGE_7);
		}
		
		if (blkstate.hasProperty(BlockStateProperties.AGE_15)) {
		return blkstate.getValue(BlockStateProperties.AGE_15);
		}
		
		if (blkstate.hasProperty(BlockStateProperties.AGE_25)) {
		return blkstate.getValue(BlockStateProperties.AGE_25);
		}
		
		return -1;
		}				
			

 

the other would be dirt your hands on the nbt data of the block and check if it have a string whit same name 

	// ##########
public String print() {
BlockState blkstate = this.getBlockState();

String json = "";

//int id = Block.getId(blkstate);

String propiedades = "";
for (Property<?> porp : blkstate.getProperties()) {

System.out.println(porp.getName() + " -> " + blkstate.getValue(porp));
propiedades += String.format( ",\"%1$s\":\"%2$s\"", porp.getName(), blkstate.getValue(porp) );
}

json = String.format("{\"blockname\":\"%1$s\",\"x\":\"%2$s\",\"y\":\"%3$s\",\"z\":\"%4$s\"%5$s}",
this.get_blkfullname(), this.pos.getX(), this.pos.getY(), this.pos.getZ(), propiedades
);

//System.out.println("\n" + json + "\n" );
return json;
}
