LÖVE

downloaded "envy" on the wiki and it doesn't work (mac os x 10.5). what am i doing wrong?

I had the same issue. Through some extensive debugging I finally found that the vector library was confusing the local variable with the class function. I don't know if this is a bug in LOVE or LUA? or even begin to explain the why, yet.

I had to change all the vector library class functions to a different name from the local variable being passed in. Works now. Thanks so much for the vector library, I spent a week trying to remember math from 10 years ago doing it myself before I found this.

I suspect that the return statement was running the local vector's new() function instead of the "top level" class? Not sure but I found something that works.

example of the change.
from--
function vector.class:distance(vector,k)
return vector:new(vector.x - self.x, vector.y - self.y):length();
end;

To...

function vctr.class:distance(vector,k)
return vctr:new(vector.x - self.x, vector.y - self.y):length();
end;

Test code I tossed into the function and put the function call into the main.lua:draw()

love.graphics.draw("v.x:"..vector.x.." self.x:"..self.x.."vector.y:"..vector.y.."self.y:"..self.y ,1,12+(k*10)) -- test 1, raw inputs
test = vector:new(vector.x - self.x, vector.y - self.y) -- test actual new vector creation, broke here before the change...
love.graphics.draw(tostring(test:length() ),1,12+k,0,2/32,2/32) -- display data

"...all the above..."

DAMN!

you're genius! I know it sounds lazy, but could you post the code? could you talk with the generator about this issue, so he could update envy officially? I'm gonna send him a privat message right now... 8-)

The download link you got there dosen't work anymore, but after meesing around I found the link that dose work: http://kuromeku.com/dump/lua/envy/ for people that don' want to go in circles just to get the frame work.

Hi everyone,

I'd like to have a look at this lib, but it seems it has been removed from kuromeku's place.

Could someone post it somewhere else? (I'd suggest the wiki, github.com or code.google.com)

Thanks and regards!

I am trying to create a "bat" type weapon... however I am really lost, because all the other weapons are projectile based. I don't know lua enough to actually know what I am looking at.

All the links that included in this subject are dead now. Sorry to say that
