How to make a boomerang like item

noobyt4 · May 15, 2019

I wanna make a boomerang like item im using the wand.zip to make it if anyone can help me thanks!

Ultroman · May 15, 2019

Why don't you study the Boomerang prefab? If you want the exact same behavior, that would be the way to go. Otherwise, you'd have to describe what you want in order for us to help you.

noobyt4 · May 15, 2019

I did put the boomerang code in the scripts .wand but all that did was make my inventor invisible i should note i deleted all the code in the wand.lua replaced it with the boomerang code and renamed everything to wand and WAND etc

I'm not sure what you mean by "make my inventor invisible"

If it's invisible in your inventory, then there's an issue with the inventory image part.
If it's invisible when you throw it, then there's an issue with the animations.
If it makes your entire inventory disappear, then you've certainly done something very wrong.

noobyt4 · May 16, 2019

Yes it makes my inventory disapear along with my health and everything

Ultroman · May 17, 2019

There must be a crash or error of something in your logs. Otherwise, you've found the cleanest way to completely disable the HUD, in which case, congratulations!

noobyt4 · May 17, 2019

Alright here wand.lua try and fix or see whats wrong i guess

Ultroman · May 17, 2019

Give me a zip with your whole mod.

noobyt3 · May 17, 2019

there i think i dont know

oh here

Ultroman · May 17, 2019

Yeah, the HUD does disappear, but the whole game also crashes. Looking at the log, we can see this is the error:

The first line says that on line 91 in wand.lua, you are using a variable called WAND_DISTANCE, which is apparently nil, in a calculation. See my newcomer post for more great information about how to debug your mods.

Also, your modinfo.lua says that the mod is DST compatible, which it is not.

Removed the dst compatible plus could you just tell me what code i need to put im not the best at following tutorials if you can't then il just follow the guide

You need to know LUA if you're going to make a mod. Making a projectile weapon isn't simple, let alone one that can return to the caster. Your current error says that you're using an undeclared variable. If your don't know what to do about that, then we're going to spend way too much time going back and forth, or I'm going to end up writing the whole mod (which I do not have time for, but others might).

I'm sure you can do it if you put in some more time. You might find it more fun than you think

noobyt4 · May 18, 2019

Fixed it the only problem i have is the images dont appear do you want the script or whole file?

noobyt4 · May 18, 2019

Also turns out the problem was lines 90,95,964 didn't have a number so i guess that was "simple"

Whole mod in a zip. Which images do not appear? There are many different images for an item mod. Is the inventory image missing? Or is it the image on the ground? Also, it seems you don't have any modicon files, or you haven't changed the filenames in your modinfo.lua

Every image doesn't appear so yeah also here

wand.zip

Ultroman · May 19, 2019

Well, first of all, your inventory image folder is not names correctly: wand\images\inventoryimages_2

It should just be inventoryimages.

You never add the inventory image or atlas to your inventoryitem component. You also do not properly include them in the "assets" list at the top of the prefab file. Please see this example mod Cactus Armor - DST.zip. It's for DST, so don't mind the extra stuff. Just look at the "assets" list and line 55 in the armor_cactus.lua.

Are you also going to add a recipe for this wand? If so, I can shared the code for that, as well.

Yes i am if you could share the code please do

i did update the file but i guess you got the old file

either way il try and fix it il update you

Ultroman · May 19, 2019

Waiting for the updated file, then.

Recipe code:

-- Recipe has the following parameters:
-- Recipe(name, ingredients, tab, level, game_type, placer, min_spacing, nounlock, numtogive, aquatic, distance, decor, flipable, image, wallitem, alt_ingredients)
-- If your image is named the same as the prefab, then you do not need to set the image manually.
-- We only set the first 4 parameters, and then ignore the rest completely.
local armor_cactus = Recipe("armor_cactus", { Ingredient("armorwood", 1), Ingredient("cactus_meat", 12)}, RECIPETABS.WAR, {SCIENCE = 1})

-- If your image is not named the same as the prefab, then you need to specify the image.
-- We only set the first 4 parameters and the image parameter, and then ignore the last 2 completely.
local armor_cactus = Recipe("armor_cactus", { Ingredient("armorwood", 1), Ingredient("cactus_meat", 12)}, RECIPETABS.WAR, {SCIENCE = 1}, nil, nil, nil, nil, nil, nil, nil, nil, nil, "armor_cactus")

-- If your atlas is also named differently, then you have to set the atlas after calling Recipe, like this:
armor_cactus.atlas = "images/inventoryimages/armor_cactus.xml"

noobyt3 · May 19, 2019

New file

also NONE of the images appear the only image that does appear is the crafting one

wand.zip

Ultroman · May 19, 2019

I see the folder name was changed, but you don't seem to have done this part:

noobyt3 · May 19, 2019

about the image or atlas part ahem how do i do it (sorry if this sounds dumb im not the best at understanding)

Ultroman · May 19, 2019

It's really simple. Download my zip file and look at armor_cactus.lua in the "scripts\prefabs" folder. Look at the "assets" list at the top of the file and look at line 55. You have the "anim" parts of your "assets" list, but the INV_IMAGE part is wrong. See how it should look like in my file. Keep in mind what the folder structure is, understand that all you're supposed to do is provide file paths for the game to the files you have, and then look at the parts I mentioned. It should pop out at you. Line 55 is almost the same thing. Just copy the lines from my mod, and make sure to change the path to have your file names in them.

I'll do it for you if you really can't get it to work, but I think you're dumbing yourself down a little or don't feel too confident in doing this. That'll never get better if you don't work at it If that's too forward, I do apologize. I just like to push people just a little bit.

noobyt3 · May 19, 2019

i can't get it to work so could you please do it im not the best at doing this if you need the new file here

wand.zip

forgot to mention this but would that fix the hand and throwing to appear?
