Scratch Algorithms You HAVE To Know!

In this Scratch Tutorial, I show some very useful algorithms that you need to be using (if you aren't already).

revolutionary stuff
Using your technique of ""move () steps" but with extra steps", I was able to create bullets that move offscreen and can travel in any direction.
And, sprinkling in a bit of my own code, I managed to make it so that they would disappear upon getting far enough away from the player.
Thank you.

[@ShiftClickLearn]

You're welcome, that's so cool! :D

[@anasoares6476]

I have a way to use movement
If then
point towards mouse pointer
move (distance to mouse pointer / 15)
end
change the number to be whatever smoothness you'd like.

This point towards X Y is a DAMN LIFE SAVER!!! I DIDNT KNOW THIS WAS EVEN POSSIBLE!!! TYSM

[@isaacler2965]

With hide/show for scrolling games easier way exist:if x position = x or y position =y show,else hide.

[@ShiftClickLearn]

I've found that it will break sometimes. a variable could be 15.1124 while the position is only 15.1. If you round it, they're both 15. :D

[@JackNoEyes]

Hello ShiftClickLearn
To say your tutorials have helped me in creating my games is a grouse understatement (there almost line for line just your tutorials). And I was wondering if you would have any idea for an algorithm relating to cloned npc's shooting cloned projectiles? This is something i've been struggling with for a while and would love to hear if you have any ideas on how to go about this.

[@shwetasimpson586]

He's on a break

[@Dam1an9X9]

so the pointing algorithm doesnt work anymore it only works if the y < y pos is true bc it doesn't let 180 / 0 it just says infinity

[@UnknownX-Edits]

Hey can you help me, Im making a game with a clone enemies in it, And I tried searching how to make clones have hitbox and nothing worked. Can you help me?

[@ShiftClickLearn]

Here's a simple way to make a hitbox:
Switch costume to the hitbox costume (Just a square that covers the player costume)
If (touching whatever) {
do whatever
}
Switch back to the player costume.
Hope this helps. :D

[@helckho3875]

for the pointing to a coordinate part, can you make it so that it will turn at a FIXED rate in the most efficient direction to the coordinate because I am making a game that will require the turning to make it less unbalanced

[@ShiftClickLearn]

That would be a good block to add...

[@MonokuroNeko77]

do you think it is also possible to change a specific number/letter in a variable to a value without modifying the other symbols?
I'm making a save function, and am using this.

[@ShiftClickLearn]

I would think it's possible... I bet you'd need to loop through each character and use a "letter i of variable". You'd also need a bunch of join blocks if I had to guess.

[@instinctdiff7765]

list will be your friend with that. put all of the characters of the value inside a list using a repeat block then modify the specific thing you want then rejoin them all again using also a repeat block. are you familiar with using lists?

[@Lukex305]

@@instinctdiff7765 you don't have to join them again with the repeat block, you can also do: set ["variable" v] to ("list" v), delete all of ["list" v]
