Following the Mouse if a Boolean is True: capitalization

[[File:Follow Mouse.png|thumb|176px|A sprite following the mouse.]]
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 [[script]]s can make sprites follow other [[sprite]]s, not just the mouse.}}

== Always Going to the Mouse ==

This script makes a sprite always be at the location of the mouse:

<scratchblocks>
when green flag clicked
forever
go to (mouse-pointer v)
</scratchblocks>

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.

<scratchblocks>
when green flag clicked
forever
point towards (mouse-pointer v)
move (10) steps
</scratchblocks>

Alternatively, the following script can be used:

<scratchblocks>
when green flag clicked
forever
glide (0.1) secs to x: (mouse x) y: (mouse y)
</scratchblocks>

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 Block|Boolean]] is '''true'''.

<scratchblocks>
when green flag clicked
forever
if <...::grey> then
point towards (mouse-pointer v)
move (10) steps
</scratchblocks>

== 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.

<scratchblocks>
when green flag clicked
forever
if <(distance to (mouse-pointer v)) < [100]> then
point towards (mouse-pointer v)
move (10) steps
</scratchblocks>

== 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.

<scratchblocks>
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
</scratchblocks>

== 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.

<scratchblocks>
when green flag clicked
forever
point towards (mouse-pointer v)
move ((distance to (mouse-pointer v)) / (12)) steps
end
</scratchblocks>

{{note|The number 12 can be increased to make the sprite follow more slowly, or decreased to make the sprite faster.}}
