Awesome mut! I like it! Thanks to you Phada. But there is a some bag...
I am using this mut on my server, and players after they death get this error from game client

Build UT2004_Build_[2004-11-11_10.48]
General protection fault!

Thanks to report this.
Can you send me the server.log? And if possible, the killlingfloor.log from a player that has crash?

 

[RoBoT]

reminds me of CoD

 

[halbridious]

It does, but this is one of those CoD reminders i don't mind

I can tell you that crash happens from this in interaction:

var Pawn P;

When pawn is destroyed, it is not set to None, instead it's left with invalid pointer so to fix this, use "local Pawn P;" instead:

function PostRender(Canvas C)
{
    local Grenade G;
    local Pawn P;

    P = ViewportOwner.Actor.Pawn;

    if ( P!=None && P.Health>0 )
        foreach P.VisibleCollidingActors(class'Grenade', G, WARN_RADIUS, P.Location, true)
            if (G != None)
                if (!class'KFNadeWarn.MutNadeWarn'.default.bOwnNadeOnly || G.Instigator == P)
                    NadeRender(C, G.Location);
}

Crash fixed.

Thank you very much to have take a look, and for this explaination

I am wondering if isn't better to put the canvas code into hud overlay instead of interaction (old ut2003 system?), I've tried and it work as well. Which one do you recommend?

If hud overlay, I should put this orange line just in case?

[...]
local Pawn P;

[COLOR=Orange]if (HUD(Owner) != None)[/COLOR]
    P = HUD(Owner).PawnOwner;

if (P != None && P.Health > 0)
[...]

Because the owner is set to HUD just after the overlay spawn while using "PC.myHUD.AddHUDOverlay(NewOverlay);".

Personally I would prefer to use HUDOverlay whenever possible and it's not necessary to check if HUD(Owner)!=None because HUD should always be there.

Thank you for advices Marco.

Update released, should be the final version if there are no more bugs.
(mediafire link remains the same but the file has been reuploaded)

I would be better if it warned you about Sirens that are closing in, and why not Bloats with low hp. That's the stuff one should worry about before throwing a grenade.

 

[Phada]

No, the aim of this mutator isn't to make the game easier.
It's mainly to prevent to blow up yourself when someone just blocked your toss, then the grenade becomes very hard to spot.

 

[RoBoT]

I have a request of few changes:
- Making an option to remove "danger word"
- Resize the grenade warn smaller.
- More transparency to the grenade warn (optional)
- Put timer when the grenade warn shows after throwing it, example.. throwing the grenade then after 1.5 second the grenade warn shows instead of covering ur screen once u throw it.

that would be great though

 

[kedirakevo]

Is this whitelisted?

nice idea!

 

[Phada]

Thanks for suggestions Robot

The danger text is already optional you can disable it in options.

The icon transparency is set around 60% and the icon size is scaled from x3 at point blank to x0.7 at the maximum warn distance, after many tests.
It's intended to be very visible, but I can easily add a option to set the icon transparency, and maybe for the max and min size.

About the timer before showing the grenade, it's a good idea, I will take a look if I can find a clean solution without modifying the grenades or pawn code himself because I wants to keep the mutator as simple as possible without modifying things to make sure he will remain 100% compatible.

@kedirakevo
I am waiting for some more feedbacks or bug reports then I will request to put this on whitelist. (that's why there is no version for now)

This mutator is awesome, if you can get it on the whitelist I'd give you delicious coo- *blows up from own grenade*

 

[Phada]

New update released, there is now a timer before showing your own grenades, set to 0.6sec by default to avoid visual spam while tossing.
I am using a special var to check the internal timer progression of the grenade, and have no idea if this will work online.
Also, the icon's transparency is configurable.

-Added Icon transparency % option as requested by RoBoT.
-Added warn delay for own nade option as requested by RoBoT.

Sweeeeet.

When you said the timer is like 0.6sec, I thought it would show up very quickly which will be the same thing, but when i tried it out its pretty good
