If we want the “Orange Dinosaur<\/strong>” to eat the “Burger<\/strong>“\u2014meaning the Burger disappears when the Dinosaur “collides<\/strong>” with it\u2014we need to use the concept of “Overlaps<\/strong>.” This allows us to program subsequent events when the images of two sprites overlap.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Please click on “Sprites<\/strong>” in the Block Toolbox<\/strong>, scroll down to find blocks related to “Overlaps<\/strong>,” and drag out the first block: “on sprite of kind (Player) overlaps otherSprite of kind (Player)<\/strong>.”<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Place this block in the Workspace<\/strong> (empty area). Since this block functions similarly to “on start<\/strong>” (it is an event handler), it cannot be placed inside other blocks, but you can place other blocks inside it.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Let’s look closely at this block. It states that when a certain Kind “overlaps<\/strong>” with another Kind, it triggers the blocks inside it.<\/p>\n\n\n\n

So, if we want the Burger to “disappear<\/strong>” when the “Orange Dinosaur<\/strong>” overlaps with the “Burger<\/strong>,” we can place the “destroy<\/strong>” block inside.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Making a specific sprite disappear is easy. In the “Sprites<\/strong>” list, there is a “destroy [mySprite]<\/strong>” block. This block will help us make the Burger vanish.<\/p>\n\n\n\n

Crucial Step:<\/strong> We need to change the logic in the overlap block to: “on sprite of kind (Player) overlaps otherSprite of kind (Food)<\/strong>.”<\/p>\n\n\n\n

Then, inside the block, drag the “otherSprite<\/strong>” value (the red rounded block representing the specific Food that was hit) into the destroy block.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Or, ensure you select the correct variable name for the burger; otherwise, nothing will happen!<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Once finished, run it in the Game Simulator<\/strong>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The “destroy [mySprite]<\/strong>” block also allows you to adjust the special effect upon destruction. Click the “+<\/strong>” symbol at the end of the block to select an “effect<\/strong>” (like fire, spray) and adjust the “duration<\/strong>.”<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Test it again in the Game Simulator<\/strong>, try switching between different effects, and find the one you like best! (*\u00b4\u2200`)~\u2665<\/p>\n\n\n\n
