Simple Kids Defence

A simple base-defence mode for the youngest players. Place the Base Heart, build walls, buy towers with coins and press Start wave!. Zombies, spiders, skeletons and creepers walk to the Heart and try to break it. Hold out, earn coins, buy more towers and get ready for the next, bigger wave.

How to play

1. Place the Base Heart. Every player gets one in the backpack until a Heart stands in the world (one per world). It has 20 hearts of health, shown as a bar at the top of the screen together with the wave number and your coins.
2. Get ready. Build walls from any blocks and place towers. Nobody can build or break blocks right next to the Heart, so it can't be sealed in.
3. Right-click the Heart to open its screen: a big Start wave! button, the Heart's health, your coins and the shop.
4. Defend! After a 10 second countdown enemies appear 25–30 blocks away and walk to the Heart. Defeat them all to win the wave.
5. Lost? No problem. The enemies vanish, the Heart heals and you start again from wave 1. Your walls, towers and coins stay.

Towers

• Towers aim on their own and never shoot into walls: they only fire when the shot can really reach the enemy.
• Towers come only from the Heart shop. A tower you break goes back to your inventory, so you can move it any time.
• The shop also sells a Heart repair for 5 coins.
• Buy buys one, Shift + Buy buys as many as you can afford.

Coins

You start with 10 coins. While a Heart stands, every hostile mob defeated by a player or a tower pays shared coins: zombies 1, skeletons 2, creepers 3, other hostile mobs 2. A creeper that explodes pays nothing. Defeated bosses pay a bonus.

Waves

• Wave 1 has 10 zombies and every wave is bigger than the one before. Spiders and skeletons join from wave 2, creepers from wave 5.
• Enemies that can't reach the Heart break the blocks in their way (see "Walls" below). This happens only during a wave and only within 100 blocks of the Heart, the rest of the world is safe.
• If you die during a wave, you come back on top of the Heart and the wave goes on.
• From wave 10 some enemies appear twice as big.

Walls

An enemy that can't reach the Heart hits the block in its way. Cracks appear and the block disappears without dropping. A stronger wall gives your towers more time.

The time depends on how hard the block is in vanilla: 1.5 seconds per point of hardness, at least half a second.

• An enemy pushed more than 1.5 blocks away from the block stops hitting it and walks on.
• Bosses break blocks twice as fast. The Zombie King breaks a whole 3×3 square at once, but it takes as long as the hardest block in it, so one obsidian block still holds the square.
• Big enemies break a passage as tall as themselves.
• Time spent breaking a wall never counts as being stuck, so walls keep working. Only an enemy that hasn't come closer to the Heart for 20 seconds without breaking anything jumps to a spot 5–8 blocks from the Heart.
• If enemies break a block in the column under the Heart, the column collapses and the Heart falls down like sand. It keeps its health, wave and coins.

Bosses

A boss arrives with a horn and a message on the screen and has its own purple health bar. Bosses come back every 20 waves, a bit stronger each time.

Good to know

• Bosses are big vanilla mobs, so the mod adds no strange new monsters, just a few blocks: the Base Heart and three towers.
• A wave in progress isn't saved. After reloading the world the same wave can be started again.
• Works well together with Simple Kids Crafting for making swords, armour and walls.

Multiplayer

The mod works in singleplayer and on dedicated servers. It must be installed on the server and on every client. All game logic runs on the server, the Heart, the wave and the coins are shared by all players.
