Alternatively, you can use the io. library. Permission will not be granted on some people's computers, however.

You could also use bash files for Windows.

How would I go about making a directory in 'Documents' ? I'm on Windows, of course.

The only place where you are allowed to write is %appdata%/yourgame.

Yet somehow I managed to write into the Documents folder, but wasn't able to make a directory there. :p

[Whatthefuck]

Also, is there a way to read all the files found in appdata/LOVE/gamename folder?
I need to save files there with varying names (user defined), but I can't find a way to actually read through all those files.

With love.filesystem.getDirectoryItems?

With love.filesystem.getDirectoryItems?

Yeah, I figured that out after I posted the question. The fact that it checked in the appdata folder as well wasn't documented, so I was confused. I added that part there in case others get confused too.

It is documented in the second line of its description.

Now I did make a thread about it, but I thought I would post here as well ^_^

http://www.love2d.org/wiki/Fixture:setFilterData

I am having some trouble understanding how to use the filterData properly. What I want to do is this:

I have a player and a monster. Both of them will be shooting projectiles.
Player should not collide with monster.
Player and monster should not collide with own bullet.
Players bullet should collide with monster and vice versa.

You get to set 3 things, categories, mask, group. But there is no real description on what the difference between them are and what they do.

Anyone who can shed some light on this?

Hi guys.

I have a very, very long code:

Code: Select all

if cam_speed_minus >= 16 then
	cam_speed_minus = 1
	elseif cam_speed_minus >= 15 then
	cam_speed_minus = 2
	elseif cam_speed_minus >= 14 then
	cam_speed_minus = 3
	elseif cam_speed_minus >= 13 then
	cam_speed_minus = 4
	elseif cam_speed_minus >= 12 then
	cam_speed_minus = 5
	elseif cam_speed_minus >= 11 then
	cam_speed_minus = 6
	elseif cam_speed_minus >= 10 then
	cam_speed_minus = 7
	elseif cam_speed_minus >= 9 then
	cam_speed_minus = 8
	elseif cam_speed_minus >= 8 then
	cam_speed_minus = 9
	elseif cam_speed_minus >= 7 then
	cam_speed_minus = 10
	elseif cam_speed_minus >= 6 then
	cam_speed_minus = 11
	elseif cam_speed_minus >= 5 then
	cam_speed_minus = 12
	elseif cam_speed_minus >= 4 then
	cam_speed_minus = 13
	elseif cam_speed_minus >= 3 then
	cam_speed_minus = 14
	elseif cam_speed_minus >= 2 then
	cam_speed_minus = 15
	elseif cam_speed_minus >= 1 then
	cam_speed_minus = 16
	elseif cam_speed_minus >= 0 then
	cam_speed_minus = 16
end

It is possible to make this in a short loop (for)?

[DaedalusYoung]

Code: Select all

cam_speed_minus = 17 - cam_speed_minus
if cam_speed_minus == 17 then
    cam_speed_minus = 16
end

No for loop needed, that would actually be more complicated anyway.

[IceQB]

Code: Select all

cam_speed_minus = 17 - cam_speed_minus

Thanks, its very simple!
