My son and me were talking about if could be possible to do an script that could be attached to an ladder to simulate that the character is climbing the ladder.
Our idea is to remove the gravity of the player, or maybe set the Y axis of the player while he is close or in front of the entity. Removing the user controls till the user reach the end of the ladder. At the same time, could be great to play the animation stored in the CGI references.
I coud not found how to manage this. Maybe there is something in the jetpack section.
Does anyone know which function could be usefull for that?
Thanks in advance

The handicap I see on player animation is that the player does not have a body, even hands when he is disarmed.
Then I think you would have to model hands an animate then as the player is climbing the ladder.
We usually using tele-transport, but something says to me that this is not what you are looking for.

Search is your friend here. There are several threads about climbing ladders

@3com. You are rigth. We are not looking for a teleport solution.
@Bored of the Rings, Thanks we already checked before. But the solution we found were changing the angle of the ladder or via teleport, but we are looking for a solution in which the player really climb the ladder.

This was my best effort ..

@synchromesh
Looks cool, it is very close to the one we want to create.

the stock character has plenty of extra animations to use for such things

using
SetFreezePosition(x,y,z)
SetFreezeAngle(ax,ay,az)
TransportToFreezePosition()
is probably the easiest method to manually control the player via script

Thanks @smallg, I tried these functions
SetFreezePosition(x,y,z)
TransportToFreezePosition()
But seems like if the player was stacked by gravity. Maybe i didn´t do it correctly.
Regarding you video.....the character recognize the ladder himself? or you programed the script to execute this animation in each zone?

TransportToFreezePosition() has to be called every frame otherwise the physics engine will take over and control the player capsule.

@Burgos
The solutions these guys have given above work just fine. No problems.
It's the recommended technique.
But if you run into issues with it, (you just wanna try something different),
a trick is to make an invisible platform that goes up or down, take a ride on
it, and animate your TP Player as they climb.
>> You gotta script the animation yourself <<

I keep myself talking than it needs the Devader's player body and/or some animated arms grabbing the stair handrail, simulating the player going up / down the ladder, to make it look realistic.
And as the icing on the cake, I would grease the ladder and use decals to simulate the player's handprints.

as amen said, need to call the commands every frame they are being updated.

yes the character could detect the ladder / windows etc and performed the action needed, not a pre-scripted sequence

I tried before post the help request. I did something very simple, only I used the
SetFreezePosition(x,y,z)
TransportToFreezePosition()
In the _main function
I did something like this:

But I said seems like if the player was attached to the ground. (the if statement is commented because I tried with and without it. I also tried the active always property to avoid the script stop running when the player is far from the object.
Thats why I asked if there is any way to remove the gravity, I realized that gravityon() off() did not work at all.

As I said is Awesome

Over- redundant question but...
This script is attached to the ladder?

Just sat down and worked out a decent ladder script (at least I think so...!)
Works better than my hidden platform one made some time back.
Enter from top or bottom both work just as well. Change height to suite--
so of course you can customize for each ladder if different heights.
{{Up to you to add animations if 3rd person}}

Test it out;

local ladderactive = {}
local moveup = {}
local playeratx = {}
local playeraty = {}
local ladderheight = {}

function ladder_init(e)
ladderactive[e] = 0
moveup[e] = 0
ladderheight[e] = 300

end -- init

function ladder_main(e)

playeratx[e] = 0
playeraty[e] = 0
if math.abs(g_PlayerPosX - g_Entity[e]['x']) < 25 then
playeratx[e] = 1
if math.abs(g_PlayerPosZ - g_Entity[e]['z']) < 25 then
playeraty[e] = 1
if ladderactive[e] == 0 then
moveup[e] = g_PlayerPosY
ladderactive[e] = 1
end
end
end

if playeratx[e] + playeraty[e] < 2 then ladderactive[e] = 0 end

if ladderactive[e] == 1 then --------- on ladder so activate climb
Prompt("Press 'A,X,D' to exit ladder")
if g_Scancode == 17 then
if moveup[e] < g_Entity[e]['y'] + ladderheight[e] then moveup[e] = moveup[e] + 2 end -- 'W' up
end

if g_Scancode == 31 then
if moveup[e] > g_Entity[e]['y'] + 35 then moveup[e] = moveup[e] - 2 end -- 'S' down
end
if g_Scancode == 45 then ForcePlayer( g_PlayerAngY + 180, 1) end -- 'X' to exit ladder
if g_Scancode == 30 then ForcePlayer( g_PlayerAngY - 90, 1) end -- 'A' left
if g_Scancode == 32 then ForcePlayer( g_PlayerAngY + 90, 1) end -- 'D' right
SetFreezePosition(g_PlayerPosX, moveup[e], g_PlayerPosZ)
TransportToFreezePositionOnly()
end --------- on ladder so activate climb

end -- main

Edit...

... "playeraty[e]"
was meant to signify 'playeratz[e]' -- z coordinate
(if you want to change that!
Didn't effect it's functionality. Been breathing too much
sheet-rock dust today... sorry.

If you want to get more complex, you can also add
if PlayerLookingAt >> ladder
Before it's climbed, but again, not sure that's necessary.

Thanks @GubbyBlips, works perfecttly!

My son wants to have also the hands, so I have a lot of work to do yet. . Bit this is a great start. I need to understand why the functions
SetFreezePosition(X, y,z)
TransportToFreezePositionOnly()
did not work for me at the begining.
Maybe because I sum the value inside the function call. I will need to check.

Again thanks.

Great job GubbyBlips !!

Tilted ladders would be a feature that could be added,
just would have to consider the angle the ladder is placed on
the map, so there would have to be variances in play...

Some old tests:

Player from first person to 3rd person switch:


NPC:

That NPC climbing the ladder looks really good Teabone.

@ bluemeenie195
G to your link https://www.youtube.com/watch?v=gXWbVKb7hX8&t=6s, RMB over the video screen a select copy video URL and then you end up with the link below:
https://youtu.be/gXWbVKb7hX8, so you have extract to all being after the last slash (/) in your case: gXWbVKb7hX8, then highlight this link, and apply it the YT tag, and you are done.

Nice,
Thanks 3com

Your welcome.

@GubbyBlips
Amazing Script !!

@GubbyBlips

Thank you for the script is it ok if i modify it slightly and add a place holder for it? so that it can be dragged onto items in a level?
My bridge support as a cage around the ladders so i cannot make it active it loses its poly shape if i do and is not climbable.
So i have attached the script to an invisible place holder and dragged it in over my ladder and it works fine

Just like hammer, the half-life editor
