It appears that the Blast Resistance plugin does not actually do anything.

In the code it is hard set to show 5F (5.0) as the value for ANY block.

This works although bedrock is shown as scientific notation (1.8E7) which could be worked around.

info.add(I18n.format("tooltip.wawla.generic.blastresist") + ": " + (data.block.getExplosionResistance(data.world, data.pos, null, null) * 5F));
