1) Create a blueprint containing a Sphere, with the help of a timeline model a bouncing ball that has no friction at all, the ball will go up and down in an infinite loop, try to play with the Curves that will demonstrate as realistically as possible a bouncing ball.
2) Create a blueprint containing a house with an entrance door, create a Sphere Collision around the door that will pick up when the player approaches the door, when the player approaches the door the door will open using a timeline (or move or rotate depending on the door you created) and when the player leaves the Sphere Collision area it will close again
3) Create a blueprint that contains something (an object or whatever you choose) that depicts a superpower,
When the player takes this power on - the game speed changes gradually from normal speed to 5x slower slow motion, the game will stay in slow motion for 3 seconds and then gradually return to normal speed using a timeline.
4) Create a super magnet -
Create 2 lorphints the first with super power, and the second with a cube in it
When the player touches the blueprint of the super power he will get the magnet power and all blueprints of the second type that contain a cube will move to the player during 3 seconds and will decrease during the movement to the size of 0,0,0
