Wither Tweaks
by the_tizio
Wither Tweaks lets server owners change how a Wither's spawn explosion treats blocks, through a config file.
What it does
By default a Wither breaks most blocks when it spawns and its charging explosion removes terrain, while tougher blocks such as obsidian usually survive. The mod exposes the settings that control this behaviour, so a server can decide whether the initial invulnerability explosion destroys blocks at all and which block hardness levels it can break, within a configured range from 0 to 2.
The mod is built for servers running Withers in farm, technical or modpack setups, where the default destruction gets in the way. Setting the explosion to off makes a Wither spawn instantly without the charging delay, and the block setting controls what the explosion can reach. Note that a second setting at 0 does not stop the Wither from breaking blocks during the initial explosion, so a Wither able to destroy anything requires both the explosion option set to false and the block level set to 0.
Wither Tweaks is installed on the server only, and players join without it. It is published for Forge and NeoForge, with files for 1.20.1 and 1.21.1, and the code is open source under the MIT License.
Key features
Explosion toggle
The initial invulnerability explosion can be switched off, so a Wither spawns without destroying terrain.
Block hardness setting
A config value from 0 to 2 sets which block hardness levels a Wither can break during its explosions.
Instant spawn option
With the explosion disabled, a Wither spawns immediately instead of after the charging time.
Config-driven changes
All of these options are adjusted in the mod's config file, so no code changes or separate builds are needed.
