I need a script for a flag that lets Link move up and down normally when Sideview Gravity is on.
I want it to work like the ladders in Link's Awakening did: when Link is standing on the flagged (walkable) combo, he can move up and down without falling. But when he moves off the combo, he'll fall.

Does anybody have what it takes to script this?

Same Here.

According to a certain Mr. Gleeok, this is on the to-do list, so it's not worth someone scripting it.

[Gleeok]

Actually, I believe it was more along the lines of "This might be on the to do list, you should check it out first."

Want a quick answer, you'll probably have to pester L about it. I'm doubting the implementation of ladder combos in 2.5 more and more these days.

In which case, I might have a look at it next week =P

How would you go about doing that Gleeok? Changing Link's Y coordinate every frame?
It's a shame we don't have control of the screen flags.

[Gleeok]

I haven't used gravity yet so i'm unsure of how L made it. The easiest way would be to set Links "float" or (Z?) if that's possible. I dunno if it'll work though. If not maybe try:

if(Link->InputUp){ Link->Y -= 0.3;}

would be the next thing i'd do, along with some ComboAt and canMove or ComboS acrobatics.

[Joe123]

Yeah, that was what I was thinking.
I, personally, wouldn't try to move Link less than a pixel though, you can't just up the systems resolution because you want sidescrolling ladders =P

[Gleeok]

Actually, storing decimals for coordinates for ffc's works great, so i've found out. I use this alot for bosses now.

...and it doesn't change the resolution silly, it just stores the data.

[Joe123]

Yes, but you can't put things to the coordinates (15,17.5) because they're pixel coordinates, and ZC can't put things at a smaller denomination than a pixel; that would require a higher resolution engine.

[Gleeok]

Well try it and see for yourself.

[Joe123]

I did...
Didn't work for Link in any case

[Gleeok]

AH, well that sucks. I was more referring to this working great on ffc's, and assumed you could do the same with Link.

..well good luck with that then!

[Joe123]

If you want to increment the movement of things by less than one pixel, you just have to do them every other frame or in smaller denominations instead.

The wait is over! A script for sidescroll ladders is finally here!

CODE

import "std.zh"

//Courtesy of Saffith, beefster09, and pkmnfrk
bool isSolid(int x, int y) {
  
  if(x<0 || x>255 || y<0 || y>175) return false;
  int mask=1111b;
    
  if(x % 16 < 8)
    mask &= 0011b;
  else
    mask &= 1100b;
  
  if(y % 16 < 8)
    mask &= 0101b;
  else
    mask &= 1010b;
  
  int ret = Screen->ComboS[ComboAt(x, y)] & mask;
  return (ret!=0);

}

ffc script ladder {
  void run(int f) {
    if(f == 0) f = 98;
    
    while(true) {
      if(Screen->ComboF[ComboAt(Link->X+8, Link->Y)] == f) {
        if(Link->Jump < 0) Link->Jump = 0;
        
        if(Link->InputDown) {
          if(!isSolid(Link->X, Link->Y + 1)) Link->Y += 1;
        }
        if(Link->InputUp) {
          if(!isSolid(Link->X, Link->Y - 1)) Link->Y -= 1;
        }
      }
      Waitframe();
    }
  }
}

The way this script works is: On every screen where you have ladders, make an invisible FFC with this script. Then put flag 98 on every "ladder" combo on that screen.
Thank you, pkmnfrk!

In case I update this (which has a non-zero chance), the script is hosted on my site:
