TextureData class
Constructors
new TextureData(Map<String, TextureInput> _textures) #
TextureData(this._textures);
Methods
bool operator ==(other) #
The equality operator.
The default behavior for all Object
s is to return true if and
only if this
and
other are the same object.
If a subclass overrides the equality operator it should override
the hashCode
method as well to maintain consistency.
bool operator ==(other) => identical(this, other);
void drawTextureAt(CanvasRenderingContext2D ctx, Coordinate location, TextureInput texture) #
void drawTextureAt(CanvasRenderingContext2D ctx, Coordinate location, TextureInput texture) { ctx.save(); final tx = new AffineTransform(); tx.translate(location.x, location.y); var theFrame = texture.frame; var source = texture.sourceColorRect.topLeft; tx.translate(source.x, source.y); if(texture.rotated) { tx.rotate(-0.5 * math.PI, 0.5 * theFrame.height, 0.5 * theFrame.height); theFrame = new Box(theFrame.left, theFrame.top, theFrame.height, theFrame.width); } CanvasUtil.transform(ctx, tx); CanvasUtil.drawImage(ctx, texture.image, theFrame); ctx.restore(); }
void drawTextureKeyAt(CanvasRenderingContext2D ctx, String textureKey, [Coordinate location = const Coordinate()]) #
void drawTextureKeyAt(CanvasRenderingContext2D ctx, String textureKey, [Coordinate location = const Coordinate()]) { assert(textureKey != null); final texture = getTexture(textureKey); assert(texture != null); drawTextureAt(ctx, location, texture); }
TextureInput getTexture(String key) #
TextureInput getTexture(String key) { assert(_textures != null); return _textures[key]; }
int hashCode() #
Get a hash code for this object.
All objects have hash codes. Hash codes are guaranteed to be the
same for objects that are equal when compared using the equality
operator ==
. Other than that there are no guarantees about
the hash codes. They will not be consistent between runs and
there are no distribution guarantees.
If a subclass overrides hashCode
it should override the
equality operator as well to maintain consistency.
external int hashCode();
noSuchMethod(String name, List args) #
noSuchMethod
is invoked when users invoke a non-existant method
on an object. The name of the method and the arguments of the
invocation are passed to noSuchMethod
. If noSuchMethod
returns a value, that value becomes the result of the original
invocation.
The default behavior of noSuchMethod
is to throw a
noSuchMethodError
.
external Dynamic noSuchMethod(String name, List args);
Type get runtimeType() #
A representation of the runtime type of the object.
external Type get runtimeType;
String toString() #
Returns a string representation of this object.
external String toString();
