Adding Sprites

[Eggplanticus]

Hi All,

 

I am new to this forum / pz modding in general. I am working on a mod I'm calling CO2, where I am trying to add things like diet pop and mentos (or Mint-O's in my mod to avoid trademark infringement) so I can make mentos bombs.

 

I wanted to add my own sprites to the game, so I started to dig around in the pz sources. After digging around in the sources I realized that there is a way to add sprites to the game:

 

1)

in the script (.txt) portion put:

Icon = spritename.png,

 

2)

put your sprite in the project zomboid *root* (parent of media) directory with name:

Item_spritename.png

 

3) Load the sprite with lua:

... function modulename.loadTextures()   local texas = getTexture("Item_spritename.png");end Events.OnGameBoot.Add(modulename.loadTextures);

 

Attached is a screenshot for proof. My diet soda icon still needs some work.

 

If we could access member texmap of the Texture class, I could make this much less hacky.

 

Actually, we just need a function like setName() that acts on member texmap instead of member textures. Then we could load the external png from a directory like media/modname/ and rename it using setName() to Item_IconName ...

aaah the getTexture still works

saw that in the priv forum but thought that was code not in the work for 2.9.9.10 anymore

think you just solved a problem a lot of item adding mods have

You sir are a legend, will be worth restoring my mod to get the few unique items back in thanks a lot buddy

So how exactly would the file look when and which file would you edit to make this happem?

[kinyoshi]

How did I not see this yesterday???

 

Now I've got to try to make textures for my mods. (sprites, whatever!!)

 

Good work Eggplanticus!!!!

I'm sure RoboMat will add it to his Tutorial here.

I can't get it to work at the moment. Maybe I'm too tired - will try again later on.

[lemmy101]

Just do:

 

Icon = Thing

 

and put:

 

Item_Thing.png 

 

in media/inventory/

Ok,

 

Just do:

and put:

 

Item_Thing.png 

 

in media/inventory/

 

Thanks, I will try this out!

 

update:

 

This does not work for me. The images are never loaded:

 

from the log:

 

WorldScreen:create

table 0x1024247087

LOADED UP A TOTAL OF 123 TEXTURES

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 

That's the normal number of textures reported.

It doesn't work for me also lemmy

hmm odd, I've used this a million times myself. :S every time we put inventory items IN in fact they are there until we pack them.

 

tho you should totally ignore the 'total of 123 textures' as it's not counting a lot and should be removed, considering there are over half a million textures

hahaha! Well, I was using it as a diagnostic to get my first implementation to work, since it increments that number for each texture I load with getTexture()

 

For whatever reason it's not automatically loading the pngs in that directory.

[lemmy101]

yeah the point is it loads the texture at the moment the inventory item is created for the first time....

 

Will look into it when I get a mo, but the method I described has worked for about 2 years since the inventory item system was first coded in :S

in which lau do i put this in? or am i to create a new one?

Doesn't seem to work for me D:

If you don't have a lua file already, create your own lua file whose only purpose is to load textures:

example co2.lua:

 

 Co2 = {}; function Co2.loadTextures()   local texas = getTexture("Item_Co2DietPopBottle.png");   texas = getTexture("Item_mintos.png");end Events.OnGameBoot.Add(Co2.loadTextures);

 

example co2.txt:

 

module Co2 {   imports {      Base   }   item MintosBomb    {        Weight = 0.9,        Type = Food,        DisplayName = Mintos Bomb,        ReplaceOnUse = PopBottleEmpty,        Icon = Co2DietPopBottle.png,    }       item DietPopBottle    {        HungerChange = 5,        Weight = 0.8,        Type = Food,        UnhappyChange = -10,        ThirstChange = -85,        DisplayName = Diet Soda,        ReplaceOnUse = PopBottleEmpty,        Icon = Co2DietPopBottle.png,    }    item Mintos    {        HungerChange = -5,        Weight = 0.1,        Type = Food,        UnhappyChange = -10,        DisplayName = Mint-O's,        Icon = mintos.png,    }    recipe Mintos Bomb {        destroy DietPopBottle,        Mintos,        Result:MintosBomb,        Time:5.0,     }}

Btw I think you don't need the local variable to use getTexture()

 

function modulename.loadTextures()   getTexture("Item_spritename.png");   getTexture("Item_2.png");   getTexture("Item_3.png");...end Events.OnGameBoot.Add(modulename.loadTextures);

 

This should work aswell

[Aricane]

Give this man a medal!

[lemmy101]

erm....

    item DietPopBottle    {        HungerChange = 5,        Weight = 0.8,        Type = Food,        UnhappyChange = -10,        ThirstChange = -85,        DisplayName = Diet Soda,        ReplaceOnUse = PopBottleEmpty,        Icon = Co2DietPopBottle.png,    } 

There is NO WAY that could possiblyy work, because in code I'm taking the contents of Icon and putting media/inventory/Item_ at the start and .png at the end and calling getTexture on it, so that would be

 

getTexture("media/inventory/Item_Co2DietPopBottle.png.png")

 

If that does work then frankly my head will explode.

It works ... I specifically had to put the .png in my script to make it work :/

 

BTW It only works when the texture is in the JAVA folder (so 'above' the media folder)

[Eggplanticus]

    item DietPopBottle    {        HungerChange = 5,        Weight = 0.8,        Type = Food,        UnhappyChange = -10,        ThirstChange = -85,        DisplayName = Diet Soda,        ReplaceOnUse = PopBottleEmpty,        Icon = Co2DietPopBottle.png,    }

You just prepend a bare "Item_" to Icon and call getTexture() on that. I think you did it to be compatible with the texture packs. That's why my hack requires part of the filename in Icon so that "Item_" + Icon results in a valid filename.

 

I got this information by decompiling the classes and looking at the function:

public InventoryItem InstanceItem(String param)

so freaking cool gj dude

It works fine for me. .

 

Edit, My bad, I posted that it worked before reading that you guys got it working
