[ZScript] Ledge climbing

[dodopod]

This mod allows the player to climb ledges by holding 'Jump'. It works using a player class derived from DoomPlayer,
so it will take some slight changes if you want to use it in Hexen, for example.

This is really cool, and seems to work pretty well.

One thing that should probably be fixed is that it doesn't check if there is enough room to climb up.

Prince of Persia Doom anyone?

One thing that should probably be fixed is that it doesn't check if there is enough room to climb up.

On the other hand, it might be better that it doesn't - sometimes you might want to just hang onto a ledge to delay a fall until something's passed by, or the platform itself could be gradually lowering and you just need to hang on for a second or so before there's enough room to get on.


edit: aww man this is sooo much cleaner than the kludgefest I'm using right now!

Mind if I take this and make some adjustments, with credit of course? I was trying to do something like this myself, and failing miserably.

That's true, though I should probably add a special case for that, or something. As it is, the player bounces up and down when they get to the top.

Sure.

New version. Now it works w/ 3D floors, and when there's not enough clearance to get on top of a ledge. The player will automatically crouch when they reach the top of a ledge, in case they need to fit into a small space. Or, if there still isn't enough room, they'll just hang on, until the player lets go.

This feels almost like Dying Light's ledge climbing mechanics. Good job!

I'm kind of a noob at ACS/Zscript how do I make it so the script works with my pre made playercharacter?

[dodopod]

I'm not sure exactly what you're trying to do, so it's hard to give precise instructions. The main thing is to find the file zscript/climbing/climbing_player.zc. The first line should say

Code: Select all

class ClimbingPlayer : DoomPlayer

Change "DoomPlayer" to the name of your player class. If that doesn't work, send me your PK3 so I can see what's wrong.

Sorry for the bump, I'm having trouble getting this to work with other classes, I've tried to do what was said bellow but whenever i replace "DoomPlayer" with the class i want i just get an error on startup, any help would be appreciated.

[dodopod]

That solution didn't end up working, anyway. What did work was to have the custom player class inherit from ClimbingPlayer. In other words

Code: Select all

class YourPlayerClass : ClimbingPlayer

But I'm not entirely sure what you're trying to do, so that may or may not work.

[Treck]

Thanks for the help, unfortunately i still cant make it work, how i have it set up

Code: Select all

class Doomer3 : ClimbingPlayer

In a separate PK3 the class is defined in KEYCONF and looks like

Code: Select all

clearplayerclasses
addplayerclass Doomer3

This is the message i get on startup if anyone can suggest what im doing wrong.

[dodopod]

Wait, did you change the line that said

Code: Select all

class ClimbingPlayer : DoomPlayer

to

Code: Select all

class Doomer3 : ClimbingPlayer

That's not what I meant. What I meant was, go to wherever Doomer3 is defined, and change that line to

Code: Select all

class Doomer3 : ClimbingPlayer

Ahh, yes, That did the trick thanks heaps, I'm really enjoying this script it works wonderful!
