Drawing help

Post by TurtleP »

Hello all,

I am trying to draw an image in this class, box.lua. However, it will not appear. I looked at the hamster ball tutorial, and still it refuses to draw!

Code: Select all

box = class:new()

function box:init(x, y)
	--PHYSICS STUFF
	self.cox = x
	self.coy = y
	self.x = x-12/16
	self.y = y-14/16
	self.speedy = 0
	self.speedx = 0
	self.width = 12/16
	self.height = 14/16
	self.static = false
	self.active = true
	self.category = 9
	self.parent = nil
	self.portaloverride = true

	self.mask = {	true,
					false, false, false, false, false,
					false, true, false, true, true,
					false, false, true, false, false,
					true, true, false, false, true,
					false, true, true, false, false,
					true, false, true, true, true}
					
	self.emancipatecheck = true

	self.userect = adduserect(self.x, self.y, 12/16, 12/16, self)
	
	--IMAGE STUFF
	self.drawable = true
	self.graphic = Turret
	self.quad = Turretquad
	self.offsetX = 6
	self.offsetY = 6
	self.quadcenterX = 6
	self.quadcenterY = 6
	
	self.rotation = 0 --for portals
	
	self.falling = false
	self.destroying = false
	self.outtable = {}
	self.portaledframe = false
end

function box:draw()
	love.graphics.draw(lazerimg, self.x, self.y)
end


function box:update(dt)

	local friction = boxfrictionair
	if self.falling == false then
		friction = boxfriction
	end
	
	if not self.pushed then
		if self.speedx > 0 then
			self.speedx = self.speedx - friction*dt
			if self.speedx < 0 then
				self.speedx = 0
			end
		else
			self.speedx = self.speedx + friction*dt
			if self.speedx > 0 then
				self.speedx = 0
			end
		end
	else
		self.pushed = false
	end
	
	--rotate back to 0 (portals)
	self.rotation = math.mod(self.rotation, math.pi*2)
	if self.rotation > 0 then
		self.rotation = self.rotation - portalrotationalignmentspeed*dt
		if self.rotation < 0 then
			self.rotation = 0
		end
	elseif self.rotation < 0 then
		self.rotation = self.rotation + portalrotationalignmentspeed*dt
		if self.rotation > 0 then
			self.rotation = 0
		end
	end
	
	if self.parent then
		local oldx = self.x
		local oldy = self.y
		
		self.x = self.parent.x+math.sin(-self.parent.pointingangle)*0.3
		self.y = self.parent.y-math.cos(-self.parent.pointingangle)*0.3
		
		if self.portaledframe == false then
			for h, u in pairs(emancipationgrills) do
				if u.dir == "hor" then
					if inrange(self.x+6/16, u.startx-1, u.endx, true) and inrange(u.y-14/16, oldy, self.y, true) then

Do you call the box:draw function in the love.draw in main.lua?

I believe so. It's a mod I'm making for Mari0 btw.

EDIT:

It's not doing anything because it "expects userdata"

Did you use box.draw() or box:draw()?

Well, I moved it into floorcollide. But it still expects userdata

Hey turtle. I'm this guy http://forum.stabyourself.net/memberlis ... file&u=159. Explain the problem more. I think you should try box:draw() or floorcollide:draw() or whatever instead of what you are doing at the moment... that's the only help i can provide.

Well either way, do I put those in box.lua? Because it's not drawing anything now.

You gotta be more specific than that.

Which file you put things in doesn't matter that much. It matters which files you require, what function you put things in and when you call those functions.

Also, if you read the rules you can see you can save us all a lot of time by uploading a .love of your game.

Alright. Enjoy some turrets that don't fire laser (more than everyone else at Stabyourself.net forums)
