Method Details

bakeVertices

public static void bakeVertices(float[] toVertices,
 TextureRegion region,
 float x,
 float y,
 float originX,
 float originY,
 float width,
 float height,
 float scaleX,
 float scaleY,
 float rotation)

Запечь вершины, чтобы использовать в Batch. Цвет не устанавливается (будет белый) - менять ячейки i * 5 + 2

Parameters:

toVertices - float[20]

prepareBezierCurve

public static void prepareBezierCurve(float[] out,
 Vector2[] points,
 int segmentCount,
 Color startColor,
 Color endColor)

Generates an array of segments for the curve, lerping between two colors Can be used for texturedMultiLine()

Parameters:

out - array of size (segmentCount + 1) * 3 for every point of the curve. Each point is represented as x, y and color where

points - Bezier curve points, array of 2 (linear), 3 (cubic) or 4 (quadratic)

segmentCount - number of segments, at least 2. Higher number = smoother curve

startColor - color at the start of the curve

endColor - color at the end of the curve

getTexturedMultiLineVertices

public static int getTexturedMultiLineVertices(float[] out,
 float width,
 TextureRegion textureRegion,
 float[] data,
 int dataStart,
 int dataLength)

Parameters:

out - must be of size ((dataLength / 3) - 1) * 20 or larger

Returns:

length of vertices array

getTexturedLineVertices

public static float[] getTexturedLineVertices(TextureRegion textureRegion,
 float startX,

 float startColor,
 float endColor)

Returns:

array of 20 floats ready to be drawn by batch
