[SOLVED] Question about Tilemap

Post by Todespreis »

Hey there! I'm trying to implement sort of a tilemap. I tried to understand the tutorial on https://sheepolution.com/learn/book/18 and i have some questions to it. So he says: "We use the variable names row and tile to make it more clear what is going on. We loop through the table tilemap, and each value is a row. We loop through the row and each value is a tile."
How do i declare row and tile? I tried it without declaraation, because i thought, it is in the ipairs function and i get an error at line 170 - i think, because the variables tile and row are not declared.

so here is my code:

Code: Select all

local player

local direction

local ground

local tilemap



function love.load()
    
    FrameDuration = 0.08
    FrameTimer = 0
    FrameIndex = 1
    FramesWalkingDown =    {
       love.graphics.newImage("/Character_Sprites/going_down_01.png"),
       love.graphics.newImage("/Character_Sprites/going_down_02.png"),
       love.graphics.newImage("/Character_Sprites/going_down_03.png"),
       love.graphics.newImage("/Character_Sprites/going_down_04.png"),
       love.graphics.newImage("/Character_Sprites/going_down_05.png"),
       love.graphics.newImage("/Character_Sprites/going_down_06.png")
    }

I think error is because of using "=" instead of "==", in "if tile = 11 then"?

That's correct, you are assigning instead of comparing in your love.draw function.
