Adding Fade To Inventory

[Springheel]

Spar, (or anyone else who knows), I'm trying to add some fade effects to the inventory icons and text. At the moment I'm just trying to get the group text to fade away after five seconds of staying on the same icon. I'm running into some problems though. I can make the text fade away the first time, but it stays that way--it no longer updates when you change to the next inventory object.

 

I need to know what the variable is that makes the icon/text visible, so that I can hopefully reset the GUI timer as soon as a new item is selected--that will allow me to add subtle fades, transitions, and eventually decorative animations. I don't know much about the coding behind the inventory though--specifically this line:

 

visible "gui::Inventory_GroupVisible"*"gui::Inventory_ItemVisible"

 

Can you explain to me how the text and item are set to be visible?

[sparhawk]

If both are set to 1 then it's visible. If either one is zero, then the result is zero, as it's a multiplication.

[Springheel]

So gui::Inventory_ItemVisible only has two possible values, 0 and 1? Hmm. Is there any way for the GUI code to know when the player switches from one inventory item to another? I assume there must be because it knows to change the icon.

 

What I'd like to do is add an onTime command to the GUI, so that I can start a timer every time the player changes to a different icon. Do you know how I can do that?

 

Just adding it to the "windowDef InventoryItemIcon " doesn't work, because that windowDef doesn't reset when a new item is selected.

 

Sorry if I'm not being clear--I don't know the proper terms for discussing code.

[sparhawk]

Yes, there is an event that is triggered when an item switch is happening. You can look at how the loot was done. But I must check if that even is also triggered for regular items, or only for custom gui items. I hadn't had time to add the info on the wiki and then simply forgot about it.

[sparhawk]

It's "inventory_item_[un]select" and should be triggered whenever an item is selected or unselected.

[Springheel]

Do you mean triggered as in it is given a value of 1 or 0? Or would it be classified as an "event"? If it's the former, then I figured this should work (it doesn't):

onTime 0 {set "InventoryItemName::forecolor" "1 1 1 1" }

onTime 5000 { transition "InventoryItemName::forecolor" "1 1 1 1" "1 1 1 0" "600" ; }

 

 

 

if ("gui::inventory_item_select" = 1)

 

{

resetTime "InventoryItemName" "0" ;

}

 

If it's an event, then I thought this would work (but it doesn't either):

 

onTime 5000 { transition "InventoryItemName::forecolor" "1 1 1 1" "1 1 1 0" "600" ; }

 

onNamedEvent inventory_item_select {set "InventoryItemName::forecolor" "1 1 1 1" }

 

I looked at the loot.gui but I didn't see anything about inventory_item_select.

[Napalm]

Umm, if statements use "if ("desktop::float1" == 0) "

 

double equals. I dunno if you did it in your code or not

[Springheel]

Yeah, it's that way in the code. I tried both one equal and two just to be sure. Neither did anything.

 

I'm stumped on this one.

[sparhawk]

Guis are a bit strange to work with. I already added this to my list of todos on the inventory, but I don't think it's a big deal though at the moment. I rather want to get the functionality working fiorst, because this is just bells and whistles.

[Springheel]

You're right, I was just hoping it was something I could work on without much help. Apparently not.

[sparhawk]

You might take a look at the previous version of Gilds inventory. Not sure if it is on SVN though because of the transition from CVS.

[Springheel]

Yeah, unfortunately it's not on SVN, and it's not on the two backup copies I have from earlier. Anyone still have a copy of it?

[sparhawk]

I still have CVS accessible. If you have still your keys around, I can enable an account for you. Of course it also means that you have to download a full copy of it again.

[Springheel]

That will take about a day or so...I think I'll wait and see if anyone happens to have a backup copy somewhere.

 

What about the last beta-release? Did it have the new inventory?

[Crispy]

I thought SVN had imported the history from CVS.

[sparhawk]

Not for the main mod. Only for the source.

 

Spring, I think the last beta still had Gilds version, but I'm not 100% sure.

Ok, here it is. Man, a lot more stuff here than the new version. It looks like Gil defined a couple new "events" for the fade--fadeIn and fadeOut. I'll have to spend some time this afternoon analyzing this and see if I can get it working with inventory_select instead.

 

If

[sparhawk]

I think you can activate the named events via scripting, so this should be possible. If not we should add it definitely, to make it more accessible for scripters.

[Springheel]

tdm_inv_opacity | float [0..1] | default "1"

Specifies the alphachannel for the inventory. It determines if and how much you can look through the inventory text and icons.

 

tdm_inv_fade_in | int | default "0"

Specifies how long it should take for the inventory until it becomes visible. 0 means that it will be immediatly visible when activated.

 

tdm_inv_fade_out | int | default "0"

Specifies how long it should take for the inventory until it bcomes invisible. 0 means that it will be immediatly invisible when deactivated.

 

I just noticed these on the wiki...are they actually useable with the current system?

[Springheel]

I'm kind of stumped here Spar, so I think I'm going to stop experimenting for the time being. I'll tell you the effects I'd like to be able to add at some point, and you can tell me if it's currently possible, and if not, store it away to do later.

 

 

1. I'd like to implement a very subtle fade in and out for the inventory icons/text as the player cycles through them (I think I could probably fade them in right now, but not out).

 

2. Have the icons be large while cycling through them, but have them shrink to their current size after 5 seconds of staying on the same icon.

 

3. Have the group and name text show up when cycling through them, but fade away after 5 seconds of staying on the same icon.

 

That's pretty much it. I think I could do all of these things if there was a named event called the moment the player 'selects' an inventory item (cycles to it or hotkeys to it), and a named event called the moment the player 'unselects' an item (cycling to the next item or selecting 'clear inventory').

Not yet. They are planned, so I already documented them, but they are not implemented.
