I posted this extension idea somewhere else but I have no idea how to make this…

Set path finding mode to [Top view v]
Set path finding mode to [Side view v]
Show path finding
Hide path finding

Path find to color [#67e94b]
Path find to [Sprite v] without touching color[#67e84b]
Path find to color[#67e84b] without touching [Sprite_2 v]
Path find to [Sprite v] without touching [Sprite_2 v]

if <Path finding [Failed v] ?> then
broadcast [Panic v]
end
if <Path finding [Succeeded v] ?> then
broadcast [Celebrate v]
end

Follow path in increments of (10)

Increments is referring to points on a graph
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
An example of use:

when green flag clicked
set path finding mode to [Top view v]
Show path finding
Path find to [egg v] without touching color[#FF0000]
if <Path finding [Succeeded v] ?> then
Follow path in increments of (15)
end
stop [all v]
