What happens to circle1 as you move your mouse from left to right?

centerX gets bigger and centerY gets smaller

centerY gets bigger and centerX gets smaller

centerX gets bigger and centerY gets bigger

centerX gets smaller and centerY gets smaller

If centerX gets bigger and centerY gets smaller when you move your mouse from left to right, then circle1 will move from...

the lower left corner of the canvas to the upper right corner of the canvas

the lower right corner of the canvas to the upper left corner of the canvas

the lower left corner of the canvas to the lower right corner of the canvas

the upper left corner of the canvas to the upper right corner of the canvas

If you need circle1 to move from the lower left corner to the upper right corner, then...

set centerX = mouseX and centerY= 400-mouseX

set centerX = mouseX and centerY= mouseX-400

set centerX = mouseY and centerY= 400-mouseX

set centerX = mouseY and centerY= 400-mouseY

If you need circle1 to move from the upper left corner to the lower right corner as the mouse moves from left to right, then...

set centerX = mouseX and centerY= mouseX

set centerX = mouseX and centerY= mouseX-400

set centerX = mouseX and centerY= 400-mouseX

set centerX = mouseY and centerY= 400-mouseY

If you need circle1 to move from the lower right corner to the upper left corner as the mouse moves from left to right, then...

set centerX = 400-mouseX and centerY= 400-mouseX

set centerX = mouseX and centerY= mouseX

set centerX = mouseX-400 and centerY= mouseX-400

set centerX = mouseY and centerY= 400-mouseY

Section 312: onMouseMove

27 questions

What happens when you move the mouse to the right on the canvas?

What happens when you move your mouse down on the canvas?

If you move the mouse to the right...

The box will move to the right because box.left will get bigger as mouseX gets bigger.

If you move the mouse up, circle c will move...

If you move the mouse down, what will happen?

The parameters in the onMouseMove() function definition are x and y. When you try to set c.centerX = mouseX, you can't because mouseX was never defined.

When you move the mouse to the right...

circle c will move to the right and down because centerX and center Y are both based on the x position of the mouse cursor.

When you move the mouse up and down...

The centerX and centerY of the circle are both set to x (which is the x position of the mouse). So, when you move the mouse up and down, nothing happens to circle c.

If you move the mouse up...

As you move the mouse up, mouseY gets smaller. As mouseY gets smaller, the top of the box will be set to a smaller value and therefore move up.

If you move the mouse down...

When you move the mouse down, mouseY gets bigger. Since box.height is set equal to mouseY, the box will get taller.

If you move the mouse to the left...

When you move the mouse to the left, mouseX will get smaller. Since box.width is set to mouseX, the box will get thinner.
