[armylad2011]

Make a table and write your items in it like this:

self.inventory[#self.inventory+1]={}
self.inventory[#self.inventory].name="Sword"
self.inventory[#self.inventory].amount=3

This will add 3 swords into your inventory. Then in PostRender you check if inventory menu is opened, and if it is you loop through inventory and draw items icons:

for i=1, #self.inventory do
context:DrawImage(Texture:Load("folderWithIcons/"..self.inventory[i].name), 100, 100+i*50)
context:DrawText(self.inventory[i].amount, 120, 100+i*50)
end

hi there thanx for the script but i have tried to sort mine out lol

 

i have restarted it all again when im on the final bit putting the item into my inventory nothing happens.

 

i have looked in the output and it says "we got the inventory Item B we place the bottle in the inventory

bottle

Loading shader "E:/leadwerks/MyGame/Shaders/Model/default.shader.....

process complete."

Are you using Aggrors scripts from his video?

If not this may help.

 

 

Maybe post your script so we can have a look.

[armylad2011]

yh im using same one

[armylad2011]

here are my scripts

[Jazz]

In function AddItemToInventory you forgot self.items=item before the return.

Aggror has all the scripts he uses for project Saturn on his website. Saves time on typos.

i just added the self.items before the return and still the same lol i also downloaded the script and used that so i know they wouldn't be any typo but for some reason its not drawing my bottle icon ? im finding it hard as im not used to Lua or c++ in the past i used a built in interface GML i think it was called it was set out different to what im used to so finding errors is abit difficult for me lol sorry to be a big pain for you guys lol

Replace the PostRender function with the script below.

 

Tell us what the output is and whether your see something on screen.

function Script:PostRender(context)

for i = 1, self.itemSlots, 1 do

context:SetColor(1,1,1)

local x = self.screenWidth - self.itemSize.x

local y = (i * self.itemSize.y) + (i * self.offset)

context:DrawRect(x,y, self.itemSize.x, self.itemSize.y)

local currentItem = self.items

if currentItem ~= nil and currentItem.texture ~= nil then

System:Print("going to draw a texture. i="..i..)

context:SetBlendMode(Blend.Alpha)

context:DrawImage(currentItem.texture, 0, 40 * i, 40, 40)

context:SetBlendMode(Blend.Solid)

end

end

end

[armylad2011]

in the system:print i have a error where you have ..1..) unexpected symbol as in the picture i sent and then in second picture i removed the symbol and got this reading from the output shown in the picture below

[AggrorJorn]

and are the inventory items drawn on the screen once you picked something up?

[armylad2011]

no just the 4 white boxes

[AggrorJorn]

Can you post an ingame screenshot?

 

It looks like the textures are missing, but I wonder why it isn't causing errors. Can you do a quick test by putting this line right after the PostRender function (assuming the location of the texture is correct):

context:DrawImage(Texture:Load("Materials/items/bottleicon.tex", 0,0, 100, 100)

[armylad2011]

iput theline of code in but not sureif i have it in the right place this error came up in the first picture

 

in the second picture i removed thatcode and done a in gameplay screen shot

[AggrorJorn]

The position and scale needs to be added:

context:DrawImage(Texture:Load("Materials/items/bottleicon.tex"), 0,0, 100, 100)

[armylad2011]

this error came up

[AggrorJorn]

Have you looked in the command reference?

http://www.leadwerks.com/werkspace/page/documentation/_/command-reference/texture/textureload-r341

 

You are missing a ')' after the texture path.

[armylad2011]

yes i have a picture drawn haha what do i do now ? its in the top left it already draws it when you start the game

 

i also was putting ")"

 

when you said but it was saying error soio kept starting the game and it finally came on so i there a glitch in the system ?

[AggrorJorn]

It was a simple test to check if the texture location was correct, and yes is was supposed to be drawn there.

Lets try out severall drawImage commands. Replace the if statement with the following:

if currentItem ~= nil and currentItem.texture ~= nil then
context:SetBlendMode(Blend.Alpha)
context:DrawImage(Texture:Load("Materials/items/bottleicon.tex"), x, y, self.itemSize.x, self.itemSize.y)
context:DrawImage(currentItem.texture, 0, 0, self.itemSize.x, self.itemSize.y)
context:DrawImage(currentItem.texture, x, y, 80, 80)
context:SetBlendMode(Blend.Solid)
end

[armylad2011]

nothing has changed

[armylad2011]

hi i was making a turret and made a new pivot for my player chest and the line of code you gave me for the draw image for my inventory have came up like this in the picture.

 

i was wondering if my inventory wasn't a parent ?

[armylad2011]
