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 drop down, 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 that's 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 it's 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 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 close and farther 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" block, a "Less Than" operator, and "Show", "Hide", and "If else" blocks.
