The "When touching (object)" Block
-
Prerequisite
Description
The “When touching (object)” block is a Hat block in the events category.
How does this block work?
This block plays the blocks attached below it when the current sprite touches another object, such as the “mouse-pointer”, the “edge” of the stage, or any other “sprite”.
You can select from these 3 options by clicking on the drop-down menu.
When touching (mouse-pointer)
If you select “mouse-pointer”
as the target object, this block will play the blocks attached below it whenever the mouse-pointer touches the current sprite.As shown in the example below, whenever the mouse-pointer (cursor) touches the jellyfish, it says “Hello”.
When touching (edge)
If you select “edge” as the target object, blocks below this block will play whenever the current sprite touches any of the 4 edges of the stage.
For example, as shown below, whenever the jellyfish touches the edge of the stage (highlighted in red in this example), it changes the costume.
When touching (sprite)
If you select any other “sprite” as the target object, the blocks below will play whenever the current sprite touches the target sprite selected.
As in the example below, whenever the jellyfish (current sprite) touches the fish (selected target sprite), it increases in size.
Note: You need to have at least two sprites in the project before you can select another sprite from the drop-down list.
