Only showing 64X63 of my map

You mean have the view stay within the boundary of the map? You'll just have to limit the view yourself.

You should be able to do it with something similar to this:

Code: Select all

local mapWidthLimit = map.width * map.tilewidth - love.graphics.getWidth()
local mapHeightLimit = map.height * map.tileheight - love.graphics.getHeight()

if x > mapWidthLimit then x = mapWidthLimit end
if y > mapHeightLimit then y = mapHeightLimit end
if x < 0 then x = 0 end
if y < 0 then y = 0 end

Wouldn't this be marginally more efficient?

Code: Select all

local mapWidthLimit = (map.width * map.tilewidth) - love.graphics.getWidth()
local mapHeightLimit = (map.height * map.tileheight) - love.graphics.getHeight()

if x < 0 then 
   x = 0
elseif x > mapWidthLimit then 
   x = mapWidthLimit 
end
if y < 0 then 
   y = 0
elseif y > mapHeightLimit then 
   y = mapHeightLimit 
end

Yes but I was mostly writing it for clarity.

This is even more efficient:

Code: Select all

local mapWidthLimit = map.width * map.tilewidth - love.graphics.getWidth()
local mapHeightLimit = map.height * map.tileheight - love.graphics.getHeight()

x = x < 0 and 0 or x > mapWidthLimit and mapWidthLimit or x
y = y < 0 and 0 or y > mapHeightLimit and mapHeightLimit or y

Error.
Attempt to compare nil with number.

I've coded something similar but it had no effect.

[Kadoba]

I can't help you unless I see the code you used.

[Rukiri]

Code: Select all

local mw = map.width - love.graphics.getWidth()
local mh = map.height - love.graphics.getHeight()

if x >= mw then x = mw end
if y >= mh then y = mh end
if x <= 0 then x == 0 end
if y <= 0 then y == 0 end

The code itself isn't much different to what you posted.

I had this placed in the desert examples update function.

[tentus]

Code: Select all

if x >= mw then x = mw end
if y >= mh then y = mh end
if x <= 0 then x == 0 end
if y <= 0 then y == 0 end

The last two lines are wrong. Should be:

Code: Select all

if x > mw then x = mw end
if y > mh then y = mh end
if x < 0 then x = 0 end
if y < 0 then y = 0 end

Also you should just use < and > rather than <= and >=, the = is redundant.

You also probably didn't define x and y, which is why it's giving you a nil compare error. I meant for that to be the translation/view coordinators.

[Rukiri]

I did go and define X, Y but didn't really change anything.

[Kadoba]

Ok. Let's try this again. What is the code that you are using and the exact line and error that it gives you?
