Hi there,
I've been using a previous version of STI in my current project and it was working fine. It was version 0.6.4, I think. As I'm getting to the point where I want to really use Tiled to design a level I decided to update to the current version.
And I have a problem with
love.graphics.scale. My implementation is very basic:
Code: Select all
local sti = require "Libs.STI"
function love.load()
...
level.load(sti)
...
end
function love.update(dt)
...
level.update(dt)
...
end
function level.draw()
...
level.draw()
...
end
function level.load(sti)
...
map = sti.new(maps/level1)
end
function level.update(dt)
...
map.update(dt)
end
function level.draw()
map:draw()
...
end
If I play with scale 1, it's fine, like this:
But if I play with scale 2, it shows only a quarter of the screen like this:
I tried to add
setDrawRange(, but it didn't change anything... I'd be really glad if someone can tell me what I do wrong.

You need to add map:resize to love.resize. sti uses a canvas now to fix a lot of scaling issues, which needs to be resized when the screen changes.

Thanks a lot!
Silly me, it was in the documentation.

Updated the documentation to be nice looking and more digestible. Whoop whoop!

i'm checking for collisions like this, but whenever i go to move my player, i get an error that looks like this -
the code i'm using to set up my player looks like this -
Code: Select all
function bolo_load()
img = love.graphics.newImage("gfx/bolo.png")
img:setFilter("nearest")
anim = newAnimation(img, 34, 38, 0, 0)
x = 0
y = 0
spd = 90
dir = 1
grassmap = sti.new("maps/grass")
grasscol = grassmap:getCollisionMap("collisions")
end
function bolo_update(dt)
if love.keyboard.isDown("up") and grasscol.data[y - 1][x] ~= 1 then
y = y - spd * dt
end
if love.keyboard.isDown("down") and grasscol.data[y + 1][x] ~= 1 then
y = y + spd * dt
end
if love.keyboard.isDown("left") and grasscol.data[y][x - 1] ~= 1 then
x = x - spd * dt
dir = -1
end
if love.keyboard.isDown("right") and grasscol.data[y][x + 1] ~= 1 then
x = x + spd * dt
dir = 1
end
end
i'm unsure why this is happening. maybe x and y are already used in the background of grasscol.data? not quite sure. any help would be appreciated!

You are having scope issues. You are using global x and y values for both you rmap indices and your movement speed.

i've changed the variable name in case of said conflicts, but i'm still getting thrown the error. did i misunderstand what you said?

Yes. bolo.x = bolo.x + spd * dt is the problem. You are changing x and y to non-indexed numbers.

sorry, i'm somewhat new to lua so i'm kind of unclear on how to fix this (i came from a GML background). i have what you have in terms of movement (bolo.x = bolo.x + spd) so i'm unsure of what to do next.
