Problem while taking data from config

Config:

Code:

Explosion-Power: 5
Bounce-Blocks: true
Explode-Multiple-TNT-Manually: true
randomX: -0.5 + (%random% * ((0.5 - -0.5) + 1))
randomY: -0.5 + (%random% * ((0.5 - -0.5) + 1))
randomZ: -0.5 + (%random% * ((0.5 - -0.5) + 1))

Source:

Code:java

    @EventHandler
    public void bounceBlocks(EntityExplodeEvent event) {
        if (bounceBlocks) {
            for (Block block : event.blockList()) {
                double randomX = Double.parseDouble(String.valueOf(config.getDouble("RandomX")).replaceAll("%random%", String.valueOf(Math.random())));
                double randomY = Double.parseDouble(String.valueOf(config.getDouble("RandomY")).replaceAll("%random%", String.valueOf(Math.random())));
                double randomZ = Double.parseDouble(String.valueOf(config.getDouble("RandomZ")).replaceAll("%random%", String.valueOf(Math.random())));
                if (explodeMultipleTNT && block.getType() == Material.TNT) {
                    ((TNTPrimed) block.getWorld().spawnEntity(block.getLocation(), EntityType.PRIMED_TNT)).setFuseTicks(1);
                } else {
                    FallingBlock falling = block.getWorld().spawnFallingBlock(block.getLocation(), block.getType(), block.getData());
                    falling.setDropItem(false);
                    falling.setVelocity(new Vector(randomX, randomY, randomZ));
                    block.setType(Material.AIR);
                }
            }
        }
    }

The TNT doesn't bounce blocks, the x,y,z = 0

 

MgMaor Are you sure you can store arithmetic operations in your .yml as numbers and just extract them like that ?

 

MgMaor You can't store a double as an equation.
