TASK 4

Problem 4) When a bullet hits a character, the character explodes and the explosion then disappears. Provide information about how to play the demonstration in Game Information.

This problem is simple.
1. create a explode sprite and name it explode.

2. add it to object and press OK.

thats the first few steps. Now:

1. click on your enemy object properties and make collision event.

2. select the bullet and in main 1 tab drag change instance.

3. type in your explode sprite name and click OK.

your done.
this problem was easy enough to work out by myself and i didn’t need to use the hints provided.

TASK 1

Problem 1:A ball bounces around a room and its direction is random. When the demo starts you can’t predict in which direction the ball will go. When the ball hits the walls you can’t predict in which direction the ball will go.

Solution: it didn’t take me that long to solve this problem because i did it last year. it’s pretty easy.
1. first create a room.
2. add ball sprites and object.
3. in the balls object window create event.
4. in the move tab select and drag the blue arrows into the actions window.
5. set the direction to random(360) and speed is up to you.
6. add collision event and choose wall.
7. in move tab select and drag bounce against objects into the actions window and click okay.
8. click ok to close object properties.
9. select the room and put the balls in the room.
10. run the game to test it.

this was easy enough for me to do it by my self so you shouldn’t have any problem.

i hope that was useful to you!
