Hello,
I'm new to scratch ,, all the projects I did were pretty basic following youtube videos from scratch channel, so probably this project I'm working on is advanced for me and I'm stuck

I need help with the script of the trolls (enemy)
1- how the clone can appear with time difference and run towards me
2- cause harm to me if I didn't shoot and they got so close to me
3-how when I shoot at it it changed skin to dead and disappear then appear somewhere else after few seconds

please help

You're going to want to have the trolls appear in different places and walk towards player

forever
wait (# :: #969696) secs // the frequency of the trolls
create clone of [myself v] // when dealing with enemies, clones are a good choice because they are easy to control
end

when I start as a clone  // Tells the clone what to do
go to x: (pick random (x1 :: #969696) to (x2 :: #969696)) y: (pick random (y1 :: #969696) to (y2 :: #969696)) // replace grey inputs with the desired numbers
forever // it wont actually run forever
next costume
change size by (2) //moves toward the player
if <<touching [the aiming target v] ?> and <mouse down?>> then
switch costume to [dead v]
wait (... :: #969696) secs
delete this clone // delete this clone
end
end
