This tutorial will explain how to make a sprite always be where the mouse is, follow the mouse indefinitely, if a button is pressed, if the mouse is too close to the sprite, or have the sprite follow at a distance.
 Tip: | These scripts can make sprites follow other sprites, not just the mouse. |
Always Going to the Mouse
This script makes a sprite always be at the location of the mouse:
when green flag clicked forever go to (mouse-pointer v)
The Draggable Sprite Feature can also be used, but this requires the user to click.
Following the Mouse Indefinitely
This script will make the sprite follow the mouse, but if one moves the mouse fast enough the sprite will lag behind some.
when green flag clicked forever point towards (mouse-pointer v) move (10) steps
Alternatively, the following script can be used:
when green flag clicked forever glide (0.1) secs to x: (mouse x) y: (mouse y)
This gives the object following the mouse a bit more of a velocity.
Following the Mouse if a Boolean is True
This script makes a sprite follow the mouse if the Boolean is true.
when green flag clicked forever if <...::grey> then point towards (mouse-pointer v) move (10) steps
Following the Mouse if a Sprite Comes Close Enough
This script will make the sprite follow the mouse, but only if the mouse-pointer comes within a certain distance of the sprite.
when green flag clicked forever if <(distance to (mouse-pointer v)) < [100]> then point towards (mouse-pointer v) move (10) steps
Following the Mouse at a Distance
This script will make the sprite follow the mouse indefinitely, but will never come to touch the mouse. One thing to notice about the script is that there is that there is a cushion zone. If the distance is between 50 and 70 then nothing will happen. This is designed so that the sprite will not jump or bounce erratically.
when green flag clicked
forever
point towards (mouse-pointer v)
if <(distance to (mouse-pointer v)) < [50]> then
move (-10) steps
end
if <(distance to (mouse-pointer v)) > [70]> then
move (10) steps
end
end
Following the Mouse Quicker as the Mouse Moves Away
This script will make the sprite follow the mouse indefinitely. As the mouse gets farther away from the sprite, the sprite will speed up until it gets closer again, and then slow down again.
when green flag clicked forever point towards (mouse-pointer v) move ((distance to (mouse-pointer v)) / (12)) steps end
| Note: | The number 12 can be increased to make the sprite follow more slowly, or decreased to make the sprite faster. |
