getVertices

public float[] getVertices()

getEarClippedVertices

public float[] getEarClippedVertices()

contains

public boolean contains(Vector2 p)

Check if a point is in the polygon. Use the math Intersector of Gdx.

Parameters:

p - point coordinates

Returns:

true if the point is in the polygon

vec2floatArray

public static float[] vec2floatArray(Vector2[] v)

Converts a Vector2 to an array of Float values. The output array contains the x and the y values of the original Vector2, each one after the other.

Parameters:

v - the array of vector to convert

Returns:

x and y values of each vectors

See Also:

for the opposite operation

float2vec2

public static Vector2[] float2vec2(float[] f)

Converts a float array to an array of Vector2. The input array must contains the x value first, then the y value.

Parameters:

f - coordinates of each vectors (x and y values)

Returns:

the converted array of vector
