Awwww maaaan I was so close to making this rad switch statement to replace an ugly if/else skyscraper that evaluated every single possibility only to realize that my switch was unable to check child classes. Can anyone think of a way to make this work?

Here's what I'm trying to replace:

Code: Select all

   else if( WhatDied.IsA('EXUBrute') || WhatDied.IsA('Brute') )
      Brutes++;
   else if( WhatDied.IsA('EXUGasbag') || WhatDied.IsA('Gasbag') )
      Gasbags++;
   else if( WhatDied.IsA('EXUKrall') || WhatDied.IsA('Krall') )
      Krall++;

   etc, etc etc


That shit sucks balls. Sure, the elses at least help terminate conditions earlier, but if you don't match ANY of the conditions, you have to check every single one of them and there's dozens. Every single time a pawn dies. In EXU2.

Yeah.

Here's what I tried to alleviate this problem:

Code: Select all

   switch( WhatDied.Class )
   {
      Case class'EXUBrute':
      Case class'Brute':
         log(self$": "$PlayerName$" killed a Brute");
         Brutes++;
         break;

      Case class'EXUGasbag':
      Case class'Gasbag':
         log(self$": "$PlayerName$" killed a Gasbag");
         Gasbags++;
         break;

      Case class'EXUKrall':
      Case class'Krall':
         log(self$": "$PlayerName$" killed a Krall");
         Krall++;
         break;

      etc, etc etc etc


Problem HERE is it evaluates classes LITERALLY, i.e. it doesn't check to see if a class is a child class the way IsA() does. Is there any way to use a switch statement with IsA() in the way I'm trying to, or am I stuck with if/else bullfuckery?

I also tried switch( WhatDied) and then did stuff like Case WhatDied.IsA('EXUBrute'):, but the syntax made UCC disappointed in me and it refused to cooperate. I'm guessing you can't have an uncertain statement in a switch case.

Traditionally also switch statements are used when cases are constants. I'm not surprised that unrealscript doesn't allow for what you are trying to do but it is inconvenient.

Also, traditionally both if else chains and switch statements are very fast in implementation (with switch statements being slightly faster some of the time). How it is implemented in unrealscript I have no clue, but if they at least tried a little bit in implementation an ugly pile of if else should be pretty quick even with EXU levels of stuff (as long as you aren't do too much else in there).

I guess that isn't quite the help you were looking for.

[Buff Skeleton]

Nah, that's fine, I was just mostly wanting to see if I could make the code... prettier :p

[.:..:]

Cant you use Mesh instead?

Code: Select all

   switch( WhatDied.Mesh )
   {
      case Mesh'BruteM':
         Brutes++;
         break;

      case Mesh'GasbagM':
         Gasbags++;
         break;

      case Mesh'KrallM':
         Kralls++;
         break;
   }

Theoretically that's a good solution, but not all subclasses of EXUGasbag, for example, actually use the Gasbag mesh :I

[Edit] Actually that's not strictly true... there are overlay meshes and an invisible Gasbag mesh underneath. I'll investigate this as a possible solution! Though it would definitely fail for, say, a custom Gasbag variant that was designed with a new mesh and new anims, etc.

Set their default Tags or Events to something and use that. Can't remember which one of those gets reset when spawned but you can always use the default Tag/Event.
Or make a struct with a list of enemy types, and pick that. myeah, there are a lot of ways around it.

[Buff Skeleton]

There's a lot I could do for EXUScriptedPawn, but I wanted to make it count the stock pawns as well (which are entirely different classes). Either way I guess the current solution isn't that bad all things considered, just a little disappointed I couldn't use a fancy switch for it

[Buff Skeleton]

Actually, I have a totally different question now I almost forgot about:

How do you override friendly fire damage scaling? If Friendly Fire is at 0% and you have a triggered map-wide destruction event that should damage anything that gets hit, regardless of whether it's a friend or foe, but you still want the instigator of that event to get credit for kills, it will scale the damage for friendlies based on Friendly Fire Scale. If you want friendlies to take 100% damage regardless of that scale, is there a way around that? MutatorTakeDamage hack or something? Or can it be done in the actor that deals the damage?

[Draco Nihil]

I would try MutatorTakeDamage because I noticed that thing tends to get called before several important steps. (like armor absorb damage being one)

A hack way would be to set everyone's team to a random value. >.,=,.>

[Buff Skeleton]

That won't work in coop; teams are irrelevant. Damage is based solely on a comparison of whether or not both the victim and instigator are bIsPlayer=True. That would also make ALL damage count 100% on friendlies, breaking friendly fire scale entirely.

[Draco Nihil]

Well if you want people to die instantly there's no stopping GibbedBy(); That of course is if you want people to die instantly regardless of friendlyfire.

However to fully get 'round friendly fire, you'd have to handle TakeDamage your own via MutatorTakeDamage and quite literally act as an override to regular TakeDamage and perform all the necessary functionality.. I'm not sure how in the execution cycle MutatorTakeDamage is apart from knowing it happens after ArmorAbsorbDamage (for whatever stupid reason) so maybe just modifying damage through that might do the trick.

I have got a big problem.
I can place a pickup on the map, then setup it's properties(how much health it grantes to me etc...)
but, what if I want that pickup to be dropped by a pawn?
I choose it as DropsWhenKilled, and that's all. Then, I can't modify the item.
I want to make a health pickup with the same mesh it has, but it should grant 1 health, and generate a strong, light blue light around it.
I want to modify it's DrawnScale to 0.5, but with the same collision.
I can't make these when i choose the pickup as the drops.
I tried to make a class beyond Super Health.
But I didn't find anything it's mode that can be set to these parameters.

Please help me, if you can.

[TheIronKnuckle]

I love that mesh suggestion. If you end up going with it make sure to comment why I'd be flipping the table if I came across that code even if it's the best way to do it

[makemeunreal]

I need that pickup very much.
But, it's a shame I can't do it.

[makemeunreal]

So, they should drop these things, but with a DrawScale of 0.5. Same collision.


It should boost your health, even if it is 100.So, it has to set to Superhealth. Also, +1 hp boost.

It's the code of the original pickup.

Code: Select all

//=============================================================================
// SuperHealth.
//=============================================================================
class SuperHealth extends Health;

function PlayPickupMessage(Pawn Other)
{
   Other.ClientMessage(PickupMessage, 'Pickup');
}



I made a subclass within, and tried to modify the code, but it has nothing to do with the items properties.
