## How is the coordinate plane used in video games?

Computers use numbers to represent a character’s position on screen, using number lines as rulers to measure the distance from the bottom-left corner of the screen. For our video game, we will place the number line so that the screen runs from 0 (on the left) to 400 (on the right).

### What is a coordinate plane in computer science?

Cartesian coordinates specify the position of points on a two-dimensional or three-dimensional plane. They are based on the coordinate system developed by mathematician and philosopher Rene Descartes. Cartesian coordinates consist of numbered lines on two or three axes, dubbed the x, y and z axes.

**What is a coordinate plane example?**

For people to use coordinate planes, they need to have a common language. By convention, we normally call the horizontal number line the x-axis, and we normally call the vertical number line the y-axis. For example, this point would be named (6, 2) since 6 is its x-coordinate and 2 is its y-coordinate.

**How do architects use coordinate planes?**

Coordinate planes can be a useful tool for architects. Blueprints are usually laid out on a coordinate grid to help identify angles and side lengths. For this interactive, you will use the distance between points on a coordinate plane to calculate the perimeter of a polygon.

## How to test your understanding of the coordinate plane?

Test your understanding of the coordinate plane. Point to the requested point on the right side of the game, so that the main character walks there. If it is correct, you will receive points in this game of Cartesian coordinates that will help you learn the coordinates and manage with the values of X and Y in the plane.

### Do you have to have all coordinates in the correct order?

Coordinates do not have to be exact but they should be in the correct order. Extending this to all four quadrants to include negative numbers is also excellent practice. Fill in the rest of the reverse-engineering table, identifying what is changing for each of your characters.

**How do you find the y coordinate of an image?**

The y-coordinate is found by running a line to the y-axis. A coordinate represents a single point, and an image is (by definition) many points. Some students will ask whether a characterâ€™s coordinate refers to the center of the image, or one of the corners.

**How to check your opponent’s coordinates in eeach?**

Wait for the fly to land on the coordinate grid, then type its coordinates, and a frog will eat it. Eeach player receives six quarks that they hide on a grid. The players use coordinates to find their opponent’s hidden quarks. You will see a red circle on the grid. Enter the co-ordinates and click “check.”
