Description

Builds a new object.

The BuildType of the builder unit in the config will determine what gets built (e.g. bomb or wall). (More info on bombs).

The builder must hold enough money to be able to afford the object it is building as defined by the config.

  • Objects can only be built one tile up, down, left or right from the builder; for more see Action Position Limits.
  • Builders objects can only build if their action cooldown is 0, for more see Cooldowns.

Signature

func (b *Bot) Build(builder *game.Object, pos game.Position)

Parameters

  • builder *game.Object: The unit object that has a unit type that is able to build. Must have a BuildType that is not BuildTypeNone in the config.
  • pos game.Position: The position to build the object at.

Return

void (nil-safe: does nothing if builder is nil)

Examples

unit := getWallBuilderUnit(g)
udata := unit.GetUnitData()
if unit != nil && udata != nil && *udata.Gems >= g.Config.WallBuildCost {
	b.Build(unit, game.Position{X: unit.Pos.X + 1, Y: unit.Pos.Y})
}
