# How to construct the game?

1. Show the coordinate system and major gridlines on the GeoGebra. 2. Define the point A manually. To do this, write the input section: A= (Rastgele(-8,8), Rastgele(-10,10)). This means that x-coordinate of point A will be between -8 and 8 and y-coordinate of the point A will be between -10 and 10. You can write any number you want. 3. Select the button tool and write the "Random Coordinate Generator" as caption and write A= (Rastgele(-8,8), Rastgele(-10,10)) in the GeoGebra Script part. Click OK. This button defines point A randomly. 4. Go to the settings of point A and be sure that "show object" is selected but "show tag" is not. 5. Drag any picture you want and drop it into the GeoGebra page. My picture is ship. Do not forget to delete the points that are created automatically. 6. Go to the settings of the picture and click "place" and be sure that center image is selected and choose point A as the center. Now, the point A was fixed to the picture. 7. Define point b manually. To do this, write the input section: b=2 and press the enter key. Double click the least number and change it as -8 and double click the most number and change it as 8. 8. Define point c manually. To do this, write the input section: c=2 and press the enter key. Double click the least number and change it as -10 and double click the most number and change it as 10. 9. Put any point on the coordinate plane and go to the "description" of this point. This point will be point B. Change its description as (b,c). Now, hide the point B. 10. Choose the "input box" and write"my guess is" as the caption and choose the point B as linked object. 11. Create a text and write "Your guess is". 12. Create a new text and write "..." 13. Go to the settings of the text "my guess is:" and click Scripting. Then, click "On Update" and write here: Eğer(A==B,DeğeriVer(metin2, "Perfect!"), DeğeriVer(metin2, "Wrong, please do your best!")) Here, if the coordinates is true, the feedback will be perfect and if it is not, the feedback will be wrong, please do your best!. You can write any feedback. Also, metin2 here is the text that I wrote "..." 14. Optional: You can change the size and color of the texts. 15. The game is ready to play!
