Skin that toggles with button?

[Springheel]

I have a model light with a separate light attached. I'd like the model to switch skins to an unlit version when a button is pressed but I want the light and model separate, and not part of the same entity. Is there an easy way to do this?

 

I tried making the model into a light entity with no light spawnarg, but it seems a light gets spawned with it anyway (though I can't find where it comes from).

 

 

[nbohr1more]

Hmm, so you aren't using the "skin_lit" and "skin_unlit" args?

[Springheel]

Do you mean as part of a light entity or just on the regular model? I've tried the former, which works fine, but then the entity spawns an additional light somehow. I didn't think the latter would work.

[Bikerdude]

Yeah, if your talking about the new 4 way ceiling light your making, just have a look at "atdm:antique_chandelier_4_globes" as that switches between lit and unlit skin for on and off etc.

But that entity comes with an attached light, which I want to avoid.

[nbohr1more]

Sounds like one of your skin defs is including a light attachment (either directly or inherited) unless there's something hard-coded happening there?

 

Post your def code and I'll peek around the SVN when I get home.

[Bikerdude]

But that entity comes with an attached light, which I want to avoid.

Than I would think its just a a case of removing the light entity from the def -

 

- "inherit" "atdm:static_electric_light_lit_quiet_base"

 

If not, nbhor should be able to figure it out for you.

[Springheel]

I've made an entity that looks like this:

 

entityDef atdm:electric_ornate_chandelier01
{
"inherit" "atdm:light_base"
"editor_usage" "ornate_chandelier01 that can be switched on and off. Entity does not include actual lights; just switches skins. Lights must be added separately."

"AIUse" "AIUSE_LIGHTSOURCE"
"lightType" "AIUSE_LIGHTTYPE_ELECTRIC" // grayman #2603


"editor_displayFolder" "Lights/Model Lights, Static/Switchable/Electric/"
"model" "models/darkmod/lights/non-extinguishable/chandelier_ornate01.lwo"

"extinguished" "0"




"skin_lit" "chandelier_ornate01_lit"
"skin_unlit" "chandelier_ornate01_unlit"


// so we can use LightOn(), LightOff().
// Switching skin does not work when triggered by a button:
"scriptobject" "tdm_light_holder"

// grayman #2603 - This stim can be turned on to have AI notice the light is off
"sr_class_1" "S"
"sr_type_1" "STIM_VISUAL"
"sr_state_1" "1"
"sr_radius_1" "500"
"sr_time_interval_1" "977" // every second or so

"noshadows" "0"
"noshadows_lit" "1"
}

 

It only inherits from light_base, which doesn't have any attached lights that I can see. Yet a light is spawned anyway. Maybe it's because of "spawnclass" "idLight"?

 

(the comment about skins not switching with a button is evidently false, because that part works)

[Bikerdude]

Its getting a light entity from the line -

 

"inherit" "atdm:light_base"

[Springheel]

Its getting a light entity from the line -

 

 

How?

 

There's nothing in "light_base" that indicates an attached light. "light_base" inherits from "light", which has the spawnclass line I mentioned above, but I see nothing else in the inheritance tree that could attach a light.

[nbohr1more]

I think you are onto something with spawnclass idLight but I'll take a look at:

 

"scriptobject" "tdm_light_holder"

 

to see if this is spawning it's own light too.

[Springheel]

I think you are onto something with spawnclass idLight but I'll take a look at:

 

"scriptobject" "tdm_light_holder"

 

 

 

Commenting that out doesn't remove the light, but does stop the skin swapping from working.

[grayman]

If the spawnclass is idLight, you'll get a light at spawn time. That is the spawnclass, after all.

[Springheel]

Is there any other option for toggling a skin on and off with a button?

[Dragofer]

Is there any other option for toggling a skin on and off with a button?

Answering that question on its own, you can use stim response on the lamp to change the skin when triggered.

[Springheel]

Does that mean all our light entities that def_attach a light actually have two lights?

[nbohr1more]

Interesting point. I was just thinking that the tdm_light_holder script itself has a light spawn in it

similar to how scripted fog lights work. That would be a nice boost if we could get rid of duplicate

lights.

[grayman]

No, because the spawnclass of those lights is something other than idLight. Typically they're an idStaticEntity.

 

If you can find an example of a light that uses a model and attaches a light (or an entity that eventually leads to attaching a light, like a candle holder with a candle in it), and its spawnclass is idLight, then it's probably creating one more light than needed, but I haven't found an instance of that, after looking at a half dozen examples.

I don't see where the tdm_light_holder script spawns lights.

I was thinking of examples like this, which def_attachs a "light_lamp_desk_03" entity.

 

entityDef atdm:lamp_desk_03_with_switch

{

"inherit" "atdm:static_light_lit_base"

"model" "models/darkmod/lights/non-extinguishable/lamp_desk_03.ase"

 

"extinguished" "0"

"noshadows_lit" "1" // turn off shadow when lit

// Let the lamp not obscure the light:

"noshadows" "1" // lit, so has no shadows

 

"editor_usage" "A small desk lamp with a switch that the player can toggle to turn the lamp on/off."

"editor_displayFolder" "Lights/Model Lights, Static/Switchable/Electric/Indoor"

 

// the lamp itself is unfrobable

"frobable" "0"

 

"def_attach" "light_lamp_desk_03"

"pos_attach" "flame" // At the attach point called "flame"...

"attach_pos_name_1" "flame" // ... which is defined here.

"name_attach" "flame" // Give it a name to pass along spawnargs

"attach_pos_origin_1" "0 0 37.6" // Offset the light a bit

"attach_pos_angles_1" "0 0 0" // rotate the light

 

"skin" "desklampshade_03"

"skin_lit" "desklampshade_03"

"skin_unlit" "desklampshade_03_unlit"

 

// attach the switch

"def_attach_2" "atdm:lamp_desk_switch"

"pos_attach_2" "switch" // At the attach point called "switch"...

"attach_pos_name_2" "switch" // ... which is defined here.

"name_attach_2" "switch" // Give it a name to pass along spawnargs

"attach_pos_origin_2" "-2 0 4.125" // Offset the switch a bit

"attach_pos_angles_2" "0 0 0" // rotate the switch

 

// add a link from the switch to the flame (self here refers to the newly spawned base lamp entity)

"add_link" "self:attached:switch to self:attached:flame"

}

[Springheel]

Ok, to answer my own question for future reference, there are two ways to do this:

 

1. Keep the attached light but set the radius to 1,1,1.

 

2. Set the entity to inherit from "atdm:static_light_lit_base". This inherits from func_static and isn't an idLight, but still has the script that allows for skin changes. Most of our lights that attach open flames do this.

[grayman]

So there's nothing I need to look at, right?

[Springheel]

Nope. It's still possible that those desk lamps might be spawning more than one light, but I don't think that's a big issue even if it is so.

[SteveL]

They won't be using more than one light. I remember discussing it last year when we were working out why the def_attach variety of entity light didn't used to respond to activation by a switch. Simple lights like desk maps can be an idLight themselves because they only need one model, the lamp. Entities like torches need two models because they have a particle effect too, so they use def attach to spawn a separate entity light which carries the particle model. The script object doesn't spawn a light either way.

[SteveL]

If you use option 2, you can def attach both your lights in the entity def, the ambient and the shadowcaster, if that's the setup you're using.
