Lesson 10 The Key to Adventure—Beta 159
Barrier Demolition
Another way to clear a barrier is to blow it up. This is more fun! The explorer happens
to be a demolition expert and gets to use dynamite to blow up the doors and other objects.
So cool! Note: the dynamite is also considered a passage key. You will do some advance
programming in a bit, but first get the basics done right.
15. In the Level 1 room, place an instance of the OBJ_Dynamite_Pack object somewhere
between the starting position and the doors, Figure 10-2.
16. Place the OBJ_Detonator_Up object in a place between the dynamite pack and the
doors. This should be in a place that will shield the avatar from the dynamite blast, like
behind a wall.
17. Open the Object Properties dialog box for the OBJ_Avatar object. You will program
this logic statement: IF the player presses the space bar, THEN create an instance of the
OBJ_Dynamite_Stick object at (16,–16) relative to the player. This will place a stick of
dynamite just above the avatar’s head.
18. Add an event for the player pressing the space bar.
19. Drag the Create Instance button from the Main 1 tab and drop it into the Actions:
column.
20. In the Create Instance dialog box, click the Self radio button, Figure 10-3.
21. Click in the Object: text box and select the dynamite stick object from the shortcut menu.
This is the object that will be created.
22. Enter 16 in the X: text box and –16 in the Y: text box.
23. Check the Relative check box and click the OK button to save the action.
24. Close the Object Properties dialog box, saving the changes.
