3. Motion Block
Motion blocks allow you to program the Sprite’s movement.
You can move it to different location, rotate, move towards the mouse or specify what you want the spike to do when it touched the edge of the stage.

2. You will learn … Make the Sprite move X, Y co-ordinates
Move in position / # of steps
Turn the Sprite
Point towards mouse
Touch the edge
Display X, Y, direction

3. Display information on stage

4. What is x, y ? Position a Sprite Specific Position - +
Positive X
Positive Y
Negative X
Negative Y + -
Specific Position
The x,y position is (0,0) at the centre of the stage. Right most is 240, left most is Up most is 180 and the down most is -180

5. Time to Reach a Position
goToXY.sb2
You can program the movement to a specific position in number of second. This will slow down the movement of the spike

7. Define / set x,y = 0,0 Position
In Costumes tab,
Vector mode ,
Move the Cross to the
Sprite to define the
(X,Y)=(0,0) position
Zeroing at centre position is done by the Zeroing tool. This will set the location of the Spite at X,Y = 0,0 . This is important as a reference so that
You X,Y programming location can be accurate and predictable.

8. Angular Position How ? Turn 0 to 360 deg or 0 to -360 degree 0 deg

9. Angular Position
Add the “set rotation style …” to position the Sprite correctly .

11. Touching Edge at Any Angle
Opposite any angle
Use Sensing block and add another 180 deg to direction
Rebound when touches edges :
top, bottom, right , left
Press Key “1”
Motion Block

12. Touching Edge at Any Angle
No rebound, stuck inside an edge depending on the starting angle
Press Key “Space”
Rebounded but stuck at the top edge as the Sprite still touches the top edge.
Press Key “2”
Move away from
