In this add-on, you’ll make the object appear only when the character is close to it. This makes the game much more challenging! Click the flag, and move the character sprite to the location where the object is hidden. Then, select the object sprite. Open the “sensing” menu, and drag out a “distance to” block. Select the main character sprite from the dropdown, then click on the block. The block displays a number. This number represents the distance between the object and the character. Move the character closer to the object, and click the block. The distance value got smaller. Move the character away from the object, and click the block again. The distance value is larger.
Use a conditional to program the object to appear if its distance to the character is less than a certain number, and disappear otherwise. Open the “control” menu, and place an “if else” block inside the “forever” loop. Then, place a “less than” operator into the condition field. Put the “distance to” block on the left side, and type a distance on the right. This example will use a distance of 100.
Open the “looks” menu. Place a “show” block in the “if” portion, and a “hide” block in the “else” portion. Test this code by moving the sprite closer and further from the object. Nice! Now the player will need to search each location in order to find the object! Now, it’s your turn!
Make the object appear only if it’s close to the sprite using a “distance to” block, a “less than” operator, and “show,” “hide,” and “if else” blocks.
