The overridden LoadContent method

The overridden LoadContent method is shown in Listing 3 .

Listing 3 . The overridden LoadContent method.

protected override void LoadContent() { //Create a new SpriteBatch object, which can be// used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice);//Load the image myTexture = Content.Load<Texture2D>("dogcropped"); //Initialize instance variablesspriteCol = 0; spriteRow = 0;frameWidth = myTexture.Width / spriteColLim; frameHeight = myTexture.Height / spriteRowLim;msPerFrame = fast; spriteEffect = flipEffect;winWidth = Window.ClientBounds.Width; }//end LoadContent

Load the image

The code to load the image, which is a sprite sheet, is the same as code that I have explained in earlier modules.

Initialization of variables

Some of the instance variables in Listing 1 were initialized when they were declared. Others couldn't be initialized when they were declared for a varietyof reasons.

Some could have been initialized in the constructor and others couldn't because the required information wasn't yet available.

I elected to initialize variables in the LoadContent method. By the time the LoadContent method executes, all of the information necessary to initialize the variables is available.

spriteCol and spriteRow

The variables named spriteCol and spriteRow will be used as counters to keep track of and to specify the column and row fora particular sprite image as shown in Figure 1 . The columns are numbered from 0 through 4 (five columns) and the rows are numbered from 0 through 1 (two rows).

frameWidth and frameHeight

These two variables specify the width and the height of an individual sprite image (see Figure 1 ). The width and the height of the individual sprite images are computed by dividing the total width of the image loaded in Listing 3 by the number of sprite images in a row and by dividing the total height of the imageloaded in Listing 3 by the number of sprite images in a column.


Listing 1 declares two variables named fast and slow and initializes their values to 175 milliseconds and 525 millisecondsrespectively. These two values are used to switch the animation frame rate between a fast rate and a slow rate by assigning one or the other value to thevariable named msPerFrame . The fast value is assigned to msPerFrame in Listing 3 to specify a fast frame rate when the animation begins.


The SpriteEffects enumeration lists the following effectsthat can be applied to a sprite when it is drawn:

  • FlipHorizontally
  • FlipVertically
  • None

The images in the raw sprite sheet shown in Figure 1 are all facing to the left. The FlipHorizontally enumeration value will be used to cause the images to face to the right when the dog is moving from left to rightacross the game window. The None enumeration value will be used to cause the images to face to the left (the default) when the dog is movingfrom right to left across the game window.

This is accomplished with the variables named spriteEffect , flipEffect , and noEffect . The value of spriteEffect is initialized to flipEffect in Listing 3 because the dog starts off moving from left to right.

sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log
I rally confuse this number And equations too I need exactly help

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
