Hey guys, for some reason I'm getting a nil error when attempting to draw the player, cannot figure out for the life of me why.
Gives me the following error:
However, when I draw the player in my objects file, it works fine:
Really stumped on this one. Any suggestions? I'll attach a .love of the whole thing too (with the player commented out of objects.lua)
Code: Select all
player = {}
function player.load()
player.body = love.physics.newBody(world, 650/2, 650/2, "dynamic")
player.shape = love.physics.newCircleShape(20) --radius of 20
player.fixture = love.physics.newFixture(player.body, player.shape, 1) --density of 1
player.fixture:setRestitution(0.2) --ball bounces slightly
end
function player.draw()
love.graphics.setColor(255, 0, 0)
love.graphics.circle("fill", player.body:getX(), player.body:getY(), player.shape:getRadius())
end
Code: Select all
Error
player.lua:12: attempt to index field 'body' (a nil value)
Traceback

function objects.load()
objects.ground = {}
objects.ground.body = love.physics.newBody(world, 650/2, 650-50/2)
objects.ground.shape = love.physics.newRectangleShape(650, 50) --width 650, height 50
objects.ground.fixture = love.physics.newFixture(objects.ground.body, objects.ground.shape)

objects.player.body = love.physics.newBody(world, 650/2, 650/2, "dynamic")

objects.player.fixture:setRestitution(0.2) --ball bounces slightly
end
function objects.draw()
--draw the ground
love.graphics.setColor(0,0,0)
love.graphics.polygon("fill", objects.ground.body:getWorldPoints(objects.ground.shape:getPoints()))
--draw the player
love.graphics.setColor(255, 0, 0)
love.graphics.circle("fill", objects.player.body:getX(), objects.player.body:getY(), objects.player.shape:getRadius())
end
