  • Field Details

    • isDirty

      public boolean isDirty
      If true, the vertex and UV arrays of this shape will be re-generated before the next draw call.

  • Constructor Details

    • Shape

      public Shape(float[] vertices, float[] uvArray)
      Creates a shape with pre-generated geometry.
      Parameters:
      vertices - The vertex array
      uvArray - The UV array

    • Shape

      public Shape()
      Creates a shape that will be generated before the first draw call.

  • Method Details

    • generate

      public void generate()
      Generates the arrays of vertices and texture coordinates for this shape and applies each modifier.

    • generateVertices

      protected abstract float[] generateVertices()
      Generates the vertex array for this shape.

      Odd elements define the x-component of the vertex and even elements define the y-component.

      Every three vertices (or six elements) define a triangle.

      Returns:
      The array of vertices.

    • generateUVs

      protected abstract float[] generateUVs()
      Generates the UV array for this shape.

      Odd elements define the x-component of the texture coordinate and even elements define the y-component.

      Returns:
      The array of texture coordinates.

    • draw

      public void draw(Renderer renderer, TextureAsset texture, Color color, float depth)
      Draws this shape using its vertex and UV arrays.
      Specified by:
      draw in interface TexturedDrawable
      Parameters:
      renderer - The renderer
      texture - The texture to draw with
      color - The color to draw with
      depth - The depth of the entity

    • getModifier

      public <M extends ShapeModifier> M getModifier(Class<M> modifierType)
      Gets the first modifier of a given type.
      Type Parameters:
      M - The type of modifier
      Parameters:
      modifierType - The type of modifier to search for
      Returns:
      The modifier of the given type, or null if there is none.

    • addModifier

      public void addModifier(ShapeModifier modifier)
      Adds a modifier to this shape.
      Parameters:
      modifier - The modifier to add

    • removeModifier
