Double Dash: a battle arena

Before you start

A Double Dash battle arena is built like a track (do the Double Dash track tutorial first), with different course data. Every retail arena has:

• 8 start points, one per player, in a ring facing the middle.
• No enemy route and no checkpoints.
• Item boxes (Block City's move about).
• Usually no respawn points.

1. Build it

1. Make the arena model, with materials named as in the track tutorial: walls round the edge, a fall where you can drop off.
2. Choose File > New > Mario Kart: Double Dash!! > Track from Model... and pick a battle slot (marked (battle), for example Block City).
3. Press Create. For a battle slot you get the 8 starts in a ring, centred on your arena and placed on its floor.

2. Course data

Open *_course.bol. The editor shows a Battle Arena badge and checks it with battle rules.

1. Drag the 8 start points where you want them, spread round the arena and facing in. Keep each one's player number.
2. Add item boxes: right-click empty canvas, Add Object Here, type GeoItemBox, then ⌘D for more.
3. Select everything and Snap to Ground.
4. Press Make Testable to fill in anything missing.

Need course data from scratch? File > New > Mario Kart: Double Dash!! > Battle Arena Course Data (BOL)... makes one with the 8 starts.

3. Play it

1. Right-click the .arc and choose Mark for Hot Swap > Mario Kart: Double Dash!! > Battle Maps, then the arena to replace.
2. Press Run, fix anything the checks find (Auto Correct where offered), and start a battle on the arena you replaced.

If it freezes

• A battle arena needs exactly 8 start points: the editor only shows the Battle Arena badge when it has them.
• Leave out checkpoints and the enemy route: they're for races.
• If an object's models are missing, accept the banner that imports them.
