Isometric Adventure Demo

What does it do?

• It demonstrates how to load and use an isometric tmx resource
• Sets up a ControlSystem that moves your character on the map

What are important aspects of the code?

These lines are key in this demo:

Move only on the isometric TileMap

This checks if the isometric tile exists at the point and moves only if it does.

var t *common.Tile
if e.SpaceComponent.Position.X >= 0 {
  t = levelData.GetTile(e.SpaceComponent.Center())
} else {
  t = levelData.GetTile(engo.Point{
    X: e.SpaceComponent.Position.X - float32(levelData.TileWidth),
    Y: e.SpaceComponent.Position.Y + float32(levelData.TileHeight),
  })
}

if t == nil {
  e.SpaceComponent.Position = prev
}
