// Example 3 - Button

//

// Draws two buttons. Clicking either will fill most of the screen with that button's color.

//

// Exercises:

// 1. Create a Button struct that contains a position and color

// 2. Migrate "blueButtonX", etc. over to use the new struct: "Button button1 = { 10, 90, Blue };"

// 3. Consolidate the repeated drawing code (before the loop) into a separate "void DrawButton(Button b)" function

// 4. Consolidate the repeated hit-testing code (inside the loop) into a separate "bool TestButton(Button b, int x, int y)" function

// 5. Add another button using your new functions

//

const int ButtonSize = 20;

void run()

{

int blueButtonX = 10;

int blueButtonY = 90;

int greenButtonX = 40;

int greenButtonY = 90;

// Draw our buttons with a nice bevel effect

DrawRectangle(blueButtonX, blueButtonY, ButtonSize, ButtonSize, DarkGray);

DrawRectangle(blueButtonX, blueButtonY, ButtonSize - 1, ButtonSize - 1, White);

DrawRectangle(blueButtonX + 1, blueButtonY + 1, ButtonSize - 2, ButtonSize - 2, Blue);

DrawRectangle(greenButtonX, greenButtonY, ButtonSize, ButtonSize, DarkGray);

DrawRectangle(greenButtonX, greenButtonY, ButtonSize - 1, ButtonSize - 1, White);

DrawRectangle(greenButtonX + 1, greenButtonY + 1, ButtonSize - 2, ButtonSize - 2, Green);

// Loop forever

while (true)

{

// Adding a short wait between "frames" is a good idea so the CPU doesn't max out at 100%

Wait(1);

// Don't do anything unless the mouse button is pressed

if (!LeftMousePressed()) continue;

int x = MouseX();

int y = MouseY();

// Check if we're clicking the blue button

if (x >= blueButtonX && x < blueButtonX + ButtonSize

&& y >= blueButtonY && y < blueButtonY + ButtonSize)
