Tasks

•   totalQuads

  quantity of quads that are going to be drawn

  property
•   capacity

  quantity of quads that can be stored with the current texture atlas size

  property
•   texture

  Texture of the texture atlas

  property
•   quads

  Quads that are going to be rendered

  property
• + textureAtlasWithFile:capacity:

  creates a TextureAtlas with an filename and with an initial capacity for Quads. The TextureAtlas capacity can be increased in runtime.

• – initWithFile:capacity:

  initializes a TextureAtlas with a filename and with a certain capacity for Quads. The TextureAtlas capacity can be increased in runtime.

• + textureAtlasWithTexture:capacity:

  creates a TextureAtlas with a previously initialized Texture2D object, and with an initial capacity for n Quads. The TextureAtlas capacity can be increased in runtime.

• – initWithTexture:capacity:

  initializes a TextureAtlas with a previously initialized Texture2D object, and with an initial capacity for Quads. The TextureAtlas capacity can be increased in runtime.

• – updateQuad:atIndex:

  updates a Quad (texture, vertex and color) at a certain index * index must be between 0 and the atlas capacity – 1

• – insertQuad:atIndex:

  Inserts a Quad (texture, vertex and color) at a certain index index must be between 0 and the atlas capacity – 1

• – insertQuads:atIndex:amount:

  Inserts a c array of quads at a given index index must be between 0 and the atlas capacity – 1 this method doesn’t enlarge the array when amount + index > totalQuads

• – insertQuadFromIndex:atIndex:

  Removes the quad that is located at a certain index and inserts it at a new index This operation is faster than removing and inserting in a quad in 2 different steps

• – removeQuadAtIndex:

  removes a quad at a given index number. The capacity remains the same, but the total number of quads to be drawn is reduced in 1

• – removeQuadsAtIndex:amount:

  removes a amount of quads starting from index

• – removeAllQuads

  removes all Quads. The TextureAtlas capacity remains untouched. No memory is freed. The total number of quads to be drawn will be 0

• – resizeCapacity:

  resize the capacity of the CCTextureAtlas. The new capacity can be lower or higher than the current one It returns YES if the resize was successful. If it fails to resize the capacity it will return NO with a new capacity of 0.

• – increaseTotalQuadsWith:

  Used internally by CCParticleBatchNode don’t use this unless you know what you’re doing

• – moveQuadsFromIndex:amount:atIndex:

  Moves an amount of quads from oldIndex at newIndex

• – moveQuadsFromIndex:to:

  Moves quads from index till totalQuads to the newIndex Used internally by CCParticleBatchNode This method doesn’t enlarge the array if newIndex + quads to be moved > capacity

• – fillWithEmptyQuadsFromIndex:amount:

  Ensures that after a realloc quads are still empty Used internally by CCParticleBatchNode

• – drawNumberOfQuads:

  draws n quads n can’t be greater than the capacity of the Atlas

• – drawNumberOfQuads:fromIndex:

  draws n quads from an index (offset). n + start can’t be greater than the capacity of the atlas

• – drawQuads

  draws all the Atlas’s Quads
