Setting up the path for the enemy
Next, we need to add the spawning green balls that are our enemy sprites, and in order to
do that we need to add the Pathfinding behavior. Pathfinding sets a path from one area to
another. We are going to use the Pathfinding functionality of Construct 2 to make the balls
move from the start to the finish line. Add a Pathfinding behavior to the green ball, as
shown in the following screenshot:
Once you have done this, go back to the event sheet and add an On start of layout event,
as shown in the following screenshot:
After that, add an action. Select the BallGreen object and select Find path as the action, as
shown in the following screenshot. In order to set the path, you have to first set it. You can
set the path to positions of objects, inputs such as touch and mouse, and specific locations.
