[SM] Morph lock

[Alisa Orlova]

Hi once again!
First of all, i want say thanks to all, who answered to my previous questions!
I found two patches, one of them was made by "InsomniaDX" and other one is "squishy_ichigo".  They are called "Morph lock" and "Morph lock edit"
First of them makes a "spring ball" just useless item, because you can't jump in ball form anymore. (After you will passed over special blocks of course)
Second patch "Morph lock edit" doesn't work correct, because you can unmorph simply using jump button.
Is it correct, or i do something wrong? How can I make this scheme?

i think you misunderstood how to use the patch..
when you want morph lock to be enabled, you have to use a BTS value of 20 on a block that samus will roll over, and you did this right.
however, you used the BTS value of 10 on the block right after that, which disables the morph lock.
you need to put that BTS 10 value on a different block than the one it's on now, because as samus rolls over both blocks the morph lock enables, then disables as she rolls down to the path you made.

tl;dr, move the BTS 10 block to the exits of both tunnels.

Yes, you need to have one of the 10's to the left of your 20, so that if players turn round, they aren't stuck in morph form.  You'll want to do this on each exit / entrance - 10 outside, 20 inside. :^_^:

Thanks guys, but it's just a Print Screen error, my apologies.
I did it right before going to sleep, and i did a mistake only when i made a Print Screen. I read a description, before i make it post, and i know how its BTS work.
Please think once again.

She's right . There is a bug in the squishy's one . I noticed it to him long time ago , but ...

Instead , you shoud use this version :

Code Select Expand

;The majority code was done by Insom. Major thanks to him for this and Kejardon for notes on RAM
;Code modified by Sadiztyk Fish to allow blocks to work in Fool Air X-ray, rather than solid blocks.
;Fixed check for springball, also added comments so you know what's going on mostly.
;BTS $0C locks the morph, BTS $0D unlocks it.


;BTS 0C locks the morphing, BTS 0D unlocks it
