Ever think of putting the following in your library?

Code: Select all

-- note: following requires that 'world' be global
function helper.newBox( t, x, y, w, h, d )	-- type, location, size [,density]
	local d		= d or 1
	local box		= love.physic.newBody( world, x, y, t )
	local shape	= love.physic.newRectangleShape( w, h )
	local fixture	= love.physic.newFixture( box, shape, d )	-- density
	return box
	end
function helper.newCircle( t, x, y, r, d )	-- type, location, radius [,density]
	local d		= d or 1
	local circle	= love.physic.newBody( world, x, y, t )
	local shape	= love.physic.newCircleShape( r )
	local fixture	= love.physic.newFixture( circle, shape, d )
	return circle
	end
function helper.newPolygon( t, x, y, v, d )	-- type, location, relative verts [,density]
	local d		= d or 1
	local poly		= love.physic.newBody( world, x, y, 'dynamic' )
	local shape	= love.physic.newPolygonShape( unpack( v ) )
	local fixture	= love.physic.newFixture( poly, shape, d )
	return poly
	end
function helper.newLine( t, x, y,  ... )	-- type, location, relative verts [,density]
	local d		= d or 1
	local body		= love.physic.newBody( world, x, y, t )
	local shape	= love.physic.newChainShape( false, ... )	-- don't close line
	local fixture	= love.physic.newFixture( body, shape, d )
	return body
	end

Then in main.lua you could do:

Code: Select all

--------------------------- rope -----------------------------
local box		= help.newBox( 'static', 400, 100, 35, 35 )
local circle	= help.newCircle( 'dynamic', 400, 150, 20 )
love.physisc.newRopeJoint( box, circle, 400,100, 400,150, 100 )

Just an idea.

Thank you. but for now the helper works more for an Editor than for code. oh yes, we can use them in the script for bodies as shortcut.

Alexar, in the gif, are you driving the car or is it the AI? Is the driving thing included in the .love in post #1?

it uses keyboard control, all interaction functions are in body--userdata. click the wheel and look up the userdata tab, you can see the magic.
all the examples are in the tutorial project. just load the project and switch to the scene.

I downloaded the .love from first post, and I get tons of "a body escaped Memoizer" errors when trying to test the topdown car example.

Also pressing "Help" in first menu causes a Lua error: bad argument #1 to utf8len (string expected, got table)

euh, i will see. but you can find the source code in my git.

Fond this problem in util.lua:

Code: Select all

function string.stripfilename(filename)
  print(filename)
    return string.match(filename, ".+\\([^\\]*%.%w+)$") -- *nix system
end

On Linux seems it should be (tested on Manjaro):

Code: Select all

function string.stripfilename(filename)
  print(filename)
    return string.match(filename, ".+/([^\\]*%.%w+)$") -- *nix system
end

Tells me it can't load incompatible bytecode. Not that there should be any to begin with - I prefer being able to read and modify the source.

Just in case you didn't know: different Lua versions generate different bytecode and more often than not they're incompatible.

please loop up the source code on my git. although, it's a mess.
