Are meshes visible in LoVE? If so, what is wrong with this?

After reading a bit about Lua, I decided to start tinkering with a program for LoVE. This proved difficult. The idea is that I simply draw a rectangle with the mouse, similar to how the desktop creates a bounding box when you click and then drag.
With this code I am expecting a purple block to appear after I release the mouse button
but nothing happens.
Does all drawing to the screen NEED to take place is love.draw?
Code: Select all
function love.load()
love.mouse.setPosition(1,1)
cpx = 1
cpy = 1
rpx = 1
rpy = 1
end
function love.update(dt)
x = love.mouse.getX()
y = love.mouse.getY()
function love.mousepressed(x,y,button)
if button == "l"
then cpx = x
cpy = y
end
end
function love.mousereleased(x,y,button)
if button == "l"
then rpx = x
rpy = y
end
end
vertices =
{
{cpx,cpy,
0,0,
255,0,255
},
{rpx,rpy,
0,0,
255,0,255
},
{cpx,rpy,
0,0,
255,0,255
},
{rpx,cpy,
0,0,
255,0,255
}
}
function love.mousereleased(x,y,button)
if button == "l"
then plop = love.graphics.newMesh(vertices, tx, "fan")
love.graphics.draw(plop, cpx, cpy)
end
end
end
function love.draw()
end
Thanks for the consideration

Not exactly an answer to the OP but from my experience and knowledge you shouldn't define love.mousepressed etc inside love.update
secondly any love.draw calls must be done in love.draw()!
so instead put the love.mousereleased etc functions outside the love.update and to draw the mesh you would need to call love.graphics.draw(plop, cpx, cpy)
inside love.draw() (first make sure plop exists, ie
I would manually reposition and work out what you provided but its abit confusing to read and reposition it all cause of the unfamiliar method you define your love.mouse### functions....

^ that and
If you really want to draw something outside of love.draw you'll need to use love.graphics.present(), but you should still draw in love.draw().

Thanks for the input guys, I made the appropriate fixes and nothing shows up when I expect it to still.
Oh, well-- It's all a learning process.

And you really should have defined a texture to be used (tx not defined).
Takes a while to become familiar with what all the settings for meshes should be.
Attached, please find a simple demo.
Probably not what you what but something to play with to see what all the parameters do.
Best

I attached a working version.
Used love.polygon instead of meshes.
I made the code easy to understand so please look at it.
