How to use existing walk/run (sprint/run sprint/walk whatever)

[Blade[UG]]

YourPawn:

// This uses the Pawn version of SetWalking instead of UTPawn
event SetWalking( bool bNewIsWalking )
{
    super(Pawn).SetWalking(bNewIsWalking);
} 

If you want to reverse the control, so that you Walk by default instead of run by default, in YourPlayerController:

// inverse the default meaning of the Run button
function HandleWalking()
{
    if ( Pawn != None )
        Pawn.SetWalking( bRun == 0 );
} 

Now, in YourPawn's defaultproperties, you set GroundSpeed= to the maximum run speed, and you set WalkingPct= a floating point percentage (between 0.00 and 1.00) that will be percent of the groundspeed that is used when walking.

You may also want to set bCanWalkOffLedges=True otherwise when walking, you will not be able to fall off ledges with drops larger than small stairs.

Cool. Thanks for this.

[daimaku]

thanks Blade[UG], good information !!

} 

Can I ask what to put in Bindings for Shift key as the command and onrelease?
Command=Setwalking ... perhaps. But what would change it back?

[Saishy]

I can't understand this, by setting bRun in player controller to 1 the pawn will start walking...

What kind of logic is that?
(I understand the code, I just wanna know why it's inversed)

[Blade[UG]]

tomacmuni: by default, it's already bound.

Bindings=(Name="LeftShift",Command="Walking") 

Saishy: SetWalking wants a True (Walking)/False (Running). The default HandleWalking defines the regular state (bRun == 0) to be running, and button down to be walking. Seems most games these days want the other way.

[Ordo]

Awesome. Implemented and works like a charm. Thanks, Blade.

[tomacmuni]

tomacmuni: by default, it's already bound.

Bindings=(Name="LeftShift",Command="Walking") 

Thanks Blade for the help ... i'm still having troubles.
I put the line above into DefaultInput.ini (right? plus a little . in front of it)
and used a groundspeed of 300 and a walk percentage of .33 in Mypawn, plus the event code you provided.
When PIE I can't see any change in speed, and the log doesn't report
shift being pressed.

[Blade[UG]]

No, you don't put that in DefaultInput, it's already there (or maybe it's in BaseInput)

Is your game using your playercontroller and pawn?

[tomacmuni]

Hmm, how do I check for sure that mypawn and myplayercontroller are being used?
I have the +ModEditPackages=MyGame in DefaultEngine.ini
Admittedly, when I do behindview with Tab I see the robot mesh not my own player mesh... so it looks like I may have missed something. Maybe my gameinfo is mucked up switching over to April version... but I'm not sure how to check really.

[Edit: oops, that was UTPlayerReplicationInfo.uc that I didn't specify my own familyinfo -- I always forget to swap it... so now I see my player. She
isn't running/walking though... so back to square one for me... sigh, 1AM.]

BasicGameQuickStart


and check in your log.

[narcissist]

Hey Blade, I think to invert the shift button

Pawn.SetWalking( bRun != 0 );

should have bRun != 1
or bRun == 0

[Blade[UG]]

oops, you're right. I copied from PlayerController rather than the derived class. oops! lol fixed it

[tomacmuni]

Left out of all steps I've ever come across for all these sprint/walk advices... in the PIE settings under View menu>World Properties>Game Type For PIE = MyGame (if it's not set then none of the above works in PIE though it probably does under Console or after cooking I guess but I never made it that far since it weren't workin' it seemed like). I set the default properties also in MyGame.uc to include, under the line: PlayerControllerClass=class'MyGame.MyPlayerControl ler' the additional line I spotted on a UDN page:
DefaultPawnClass=class'MyGame.MyPawn' ... funny I missed it, but not sure how relevant it is to this problem.

Now I am getting the Sinsal keystroke sprint/walk speed change.
The Blade[UG] one using walkpct doesn't seem to be kicking in, but anyway, 1 out of 2 is still a pass.

[Blade[UG]]

If you haven't completed even the most basic steps to getting your code to work, you're going to be frustrated no matter what you do.

How isn't setting up the proper pawn relevant? This requires changes to both your Pawn and PlayerController, if you're extending UT classes.

[Saishy]

oops, you're right. I copied from PlayerController rather than the derived class. oops! lol fixed it

That explains everything.

[Luke Codewalker]

Thanks Blade, I was wondering why WalkingPct didn't do anything.
But it's more than a myracle to me how this works becuase i fail to trace it back to the root.
I try to toggle my leftThumbstick, so the player keeps running until "something" happens.
I don't want to write a new function when one line of code would change this, but I crawl through every class and can't find anything. (It's like this function comes out of nothing)

[Blade[UG]]

what part isn't clear?

[Luke Codewalker]

well, the event SetWalking, bNewIsWalking and bIsWalking are the only vars i've got and i don't know where they change my GroundSpeed. So i get bad a feeling trying to write a function which toggles my input while in background some other "unknown" function is going to change my GroundSpeed.
It just confuses me right now.

(bNewIsWalking changes constantly and makes it hard for me to alter this code)

[vahid67]

hi
can anybody write a tutorial for when player pressed left shift character running and when released character walking...
thank you ,,,,

[Luke Codewalker]

ok, a friend and i found the culprit which caused (my) bNewIsWalking to change continuously. so no confusion anymore

therefore i'd like to share the "toggling code"

var        bool    bToggler; 

event SetWalking( bool bNewIsWalking )
{
    if ( bNewIsWalking != bToggler )
    {
        if( bNewIsWalking )
            bIsWalking = !bIsWalking;
        bToggler = bNewIsWalking;
    }
}

or this code if you want to start with running speed

var        bool    bToggler;

event SetWalking( bool bNewIsWalking )
{
    if ( bNewIsWalking == bToggler )
    {
        if( !bNewIsWalking )
            bIsWalking = !bIsWalking;
        bToggler = !bNewIsWalking;
    }
}

hope someone will find it usefull.

EDIT: but i still don't know where this changes my GroundSpeed and multiplies it with WalkingPct. If someone knows, please response. thanks

[Blade[UG]]

It doesn't change ground speed. Ground speed is the max speed you can go and walking pct is the percent of that that you can go when walking is true

[vahid67]

i found a tutorial and it's worked for me ...

Here

[Blade[UG]]

Your example code there, Luke, does -exactly- what the original code does, just adding an extra variable to do it. I'd guess you missed something in the OP.

[Luke Codewalker]

of course blade you are right, as i mentioned before, i don't want to write an extra function if one line of code would do me the favor. i know walkingpct is the percentage of groundspeed, but somewhere it must be processed (and change the velocity) and that's what i'm looking for. (sorry if i didn't make myself clear. what's an OP?)
greetings

[Blade[UG]]

That's on the native side of PHYS_Walking. OP = original post

You'd still need the HandleWalking() in the player controller, i'm curious as to what that solves, I don't see it.

[donamin]

thanx Blade[UG]

[Luke Codewalker]

@blade, why do i need the HandleWalking()? (it just works fine without or did i miss something?!).
for PHYS_walking it helps solving my lacks of understanding
i don't want to change some vars without getting to know how they are applied. it's a personal urge to know what's going on and how it's going on when i change something. hope you'll understand

[Blade[UG]]

Well, here's how it works. Every tick, HandleWalking() is called. That sets Pawn.bIsWalking every tick. In UTPlayerController, HandleWalking forces bIsWalking to be off. So, every tick, you're both setting, and unsetting bIsWalking. And that's why you've had to write it in SetWalking -- the reason you had problems with it, is because you didn't follow directions

[kg777]

i notice that the animation stays the same , legs go same speed in run or walk .

would i change this using the animtree ? . create a walk node .

thanks.

[Blade[UG]]

I think most people use a blend by speed.

[Blade[UG]]

Forgive me for bumping this with no new information, but was just talking about it on an IRC chat, and realized that the post is approaching 2 years old, and thought maybe some new people could use the information.

[zoix]

Thanks. What would be even more awesome is someone adding a walking animation to the characters that come with UDK
