Introduction

■ User Interface rooms: the scenes (levels) in

which the objects live backgrounds: the images used

as background for the rooms objects: the things in the game

• instances: one particular occurrence of an object

sprites: images that are used to show the objects

sounds: these can be used in games, either as background music or as effects

scripts: small pieces of code that can be used to extend the possibilities of your game

Maze Game

■ Add 2 rooms : Set the room size to be 480x480 pixels and set the grid to be 32x32 pixels

■ adding 3 sprite sprWall sprPerson sprTarget

■ Create objects Now create a wall object: Name it objWall

• Use the wall sprite• Make it solid (so things can't pass through it)

Create the person object : Name it objPerson• Use the person sprite

Create a target object : Name it objTarget• The target object should not be solid, as the player needs to be able

to move on top of it.  When the player collides with the target object, the game will continue on to the next room.

Maze Game

■ Set up movement for the person Add an event to the person object for the Keyboard  <Left>

• Add the action from the Control tab 'If instance is aligned with grid‘

• Set the snap horizontal and snap vertical to be 32 pixels.

• Add a start moving in direction

• Set the direction to be left and speed to be 4 Add actions for the up, down and right keys.  (You can use the

duplicate event option to make this job easier) To stop the person moving

• add actions for the <No Key> event

• Click the centre block in the 'Start moving in a direction' options.

Maze Game

■ Set up collision handling If the person collides with a wall it should stop, so add a

collision event

Add a collision event to the target object for a collision with objPerson

Maze Game

■ Draw 2 maze-like rooms making sure that you have walls all around the outside.  Place the person and target at the beginning and end of your

maze

Monsters

■ Add in 2 sprites one facing left and the other facing right objMonsterleft, bjMonsterRight Make a monster object : objMonster

■ Add a create event for objMonster Add in a Start Moving action make it start moving to the right.

■ Add a collision event for objMonster add in the following actions:

Paths are another way of doing the same thing, but without using collisions with blocks to turn the monster around.

Maze Game 2

■ To make the maze more interesting, we should be collecting diamonds along the way.  A door stops the person from getting to the target.  When all

the diamonds are gone, the door disappears. The target does not appear in the room until all the diamonds

are collected. 

■ Add 2 new sprites sprDoor and sprDiamond 

■ Add 2 new objects objDoor and objDiamond.  Make the door solid as it acts like a wall

Maze Game 2

■ Add sounds for picking up the diamonds : sndDiamond for opening the door : sndDoor.

■ Place diamonds around your maze. The objDiamond should have a collision event with the

person It should then play the diamond sound and destroy itself

Maze Game 2

■ Place the door so that it blocks access to the target Don't put any diamonds on the other side of the door!

■ In the person object add a collision event with the door object, stopping the

person and aligning it with the grid.  Just the same as you did with the wall object

■ When all the diamonds are gone, the door should play a sound and destroy itself.  Add the step event to the door object Add the 'If the number of instances is a value' action.  (On the

Control tab) Choose these options:

Step event : occurs once for every step of the game, which is usually 30 times a second.

Maze Game 2

play a sound and destroy the door if there are no diamonds left

add block markers to our actions

■  Save and play your game to test whether it works as expected.

Maze Game 2

■ The Target Marker use a target that does not appear in the room until all the diamonds

are collected

■ Create a marker sprite and object.  Call them sprMarker and objMarker.  Make it invisible by unchecking the Visible option.

■ use the step event add an action 'If the number of instances (of the diamond) is zero, 

Change the Instance to change the marker to the actual Target object

■ Place the target marker in the room where you want the target to appear.
