////////////////////////////////////////
// Demonstration code for wall placement
////////////////////////////////////////

// Some general notes to the arguments:

// First all the place functions take the coordinates needed to place the wall
// X and Y coordinate are taken in seperate arguments like in placeObject
// Their meaning differs for different placement methods but are mainly self explanatory
// placeLinearWall takes 4 arguments here (2 coordinates) for startX, startY, targetX and targetY

// The next argument is always the 'wall' definition, an array of wall element type strings in most cases
// That looks like ['endLeft', 'wall', 'tower', 'wall', 'endRight', 'entry', 'endLeft', 'wall', 'tower', 'wall', 'endRight']
// For placeCircularWall and placeLinearWall only wall parts are needed like: ['tower', 'wall']
// They will automatically end with the first wall element if that makes sense (e.g. the wall is not closed)
// NOTE: They take further optional arguments to adjust this behaviour (See the wall_builder.js for that)
// placeFortress just takes a fortress type string that includes the wall definition
// The default fortress type strings are made for easy placement of predefined fortresses
// They are chosen like map sizes: 'tiny', 'small', 'medium', 'normal', 'large', 'veryLarge' and 'giant'
// NOTE: To place a custom fortress use placeCustomFortress instead
// It takes an instance of the Fortress class instead of the default fortress type strings

// The next argument is always the wall style string
// Wall styles are chosen by strings so the civ strings got by g_MapSettings.PlayerData[playerId - 1].Civ can be used
// Other styles may be present as well but besides the civ styles only 'palisades' includes all wall element types (yet)

// The next argument is always the index of the player that owns the wall.
// 0 is Gaia, 1 is Player 1 (default colour blue), 2 is Player 2 (default colour red), ...

// The next argument is an angle defining the orientation of the wall
// placeLinearWall does not need an angle since it's defined by startX/Y and targetX/Y
// Orientation works like the angle argument in placeObject
// 0 is always right (towards positive X)
// Raising the angle will rotate the wall counter-clockwise (mathmatical positive in default 2D)
// PI/2 faces top (positive Y)
// Orientation might be a little confusing for placeWall since it defines where the wall has its 'front' or 'outside' not the direction it will be build to.
// It's because all other methods work like that and it's intuitive there
// That means the walls outside by default (orientation = 0) faces positive X and (without bending wall elements) will be build towards positive Y

// Some other arguments are taken but all of them are optional and in most cases not needed
// One example is maxAngle for placeCircularWall that defines how far the wall will circumvent the center. Default is 2*PI which makes a full circle
