Coding Platformer Enemies | 11. Scratch Platformer Tutorial

Coding Platformer Enemies made easy. In this tutorial we show how to add multiple patrolling, chomping enemies to our Scratch Game.
Jump on their heads to squash them and continue on your quest!
We also add safe zones to allow for guided patrolling, and learn about the danger of placing enemies too near the edge of a scene where the player might unfairly lose a life.
My tutorials are for all budding game & software developers using Code Blocks. Scratch On guys!

This series is helping me out a ton, because I'm making a platformer in Pocket Code,so most things also work on it.

[@namrata.agarwal]

Pocket code is dum

[@studiodespenates]

I implemented those enemies and they give a really cool touch to the game. Thank you very much. I'm gonna try to handle the player hitbox because the death by ennemies is quite sensitive

[@studiodespenates]

@griffpatch , I tried two ways (that did work) of implementing the use of a hitbox for the player and I need some advice. The first one was to broadcast a new event "Touching Enemy" instead of "lose life" in the "Touching Player" block in the enemy. The Player receives this event, changes costume to the hitbox and deals wether the hitbox really touches the enemy clone and then broadcast lose life or not. As I said, it did work but it seems a bit messy as the check for touching danger happens in the "Tick last" event receiver. I'm afraid this could mess up with the costume change to hitboxes as two different scripts can now change costums to hitbox and check for collision with dangers ans enemies. (I did not mention that I added a hitbox for the "touching danger" in the "tick last" too cause, it was also a little bit sensitive with danger sprite ;-) ) So I tried another solution of having a new "for all sprites" variable named "TOUCHING ENEMY". It is set to 1 by the enemy clone instead of broadcasting "lose life". The player, in the "tick last" event receiver can now check the TOUCHING ENEMY variable value and do the hitbox costume trick in that script. Which keeps the costume hitbox and check for collision with danger and enemy a little more tidy. Then at the end of "tick last" receiver, the variable is set to 0 if the player is not touching an enemy. There might be a better place to reset the variable which I haven't found yet. I'd rather like the second solution with the variable but I'm not sure. Both those implementations involves 2 sprite touching tests (one in the enemy clone, one in the player) which is not very effective. Which solution seems better to you and why? Or am I in the wrong direction? Thanks a lot.

You could add another way to defeat enemies in a future tutorial. Such as.. a sword! Or maybe a shooting weapon. (Because that is what i'm dealing with at the moment) Another thing you can add is enemies with multiple lives (Not exactly like a Paragoomba for example, but with health that is (in)visible), or even a boss!

[@rodgeangeroancelso6109]

I think a boss would be fine for my project

[@smth35]

@@rodgeangeroancelso6109 yeah, i have already developed a shooting at enemies mechanic. I might also add metal body/helmet to enemies. Also, multiple health can be done by setting a local variable to a number at the start of "when start as clone", and change health by -1 when normally the enemy should be squashed. And squash the enemy if enemy hp is below 1 after changing the hp.

[@smth35]

A custom moveset can be made in the enemy loop

[@bitofbeans]

BOTH OF THESE METHODS CHECK ONE LETTER AT A TIME make one empty costume and then 26 costumes called A,B,C etc switch costume to (empty costume) switch costume to ((letter variable)) if costume is not empty costume it is uppercase, otherwise lowercase ORRRRR if you don’t want to make 27 costumes, you can a make a bit more code, don’t worry it’s a lot easier to make imo make one costume that is empty and one costume named ABCDEF… all the way to Z ( all letters uppercase) then a variable named Characters and set it to A to Z all uppercase again and a variable called String also any counter variable works, like “i” or “counter” now set counter to 1 and string to nothing repeat 26 if letter (counter) of (Characters) = the character you are checking then set string to (string) join (character you are checking) else set string to (string) join (letter (counter) of (Characters) to finish the repeat loop add a change counter by 1 AFTER the repeat loop set costume to empty costume set costume to string if costume is empty costume then it is lowercase, otherwise it’s lowercase hope this helps!!

@@bitofbeans I'm gonna try it!

[@happyretirementmsvacca]

two suggestions: 1. Instead of a 1 + floor of frame mod 4, could we have done a join Red and floor of frame mod 5? 2. Instead of a change speed y by -1, should we have used the already existing gravity variable?
