flowers and sheep: ecology game, newbie needs help

[Clödi]

Hi,

i am a very inexperienced coder, so i guess i made an obvious mistake. Maybe someone could give me an easy way i can find out on which line my code crashes, in that way i might have to ask for help less often.

This is my code, i want it to grow flowers. Next step would be growing them in random directions. And then sheep eating them. But i only got them on the map, that was the best i could do.

Code: Select all

function love.load()

--debug variablen

koll = 0

-- map variables
   map_w = 40
   map_h = 80
   map_x = 0
   map_y = 0
   map_offset_x = -22
   map_offset_y = -22
   map_display_w = 20
   map_display_h = 20
   tile_w = 22
   tile_h = 22
   
-- blume

	flowergraphic = love.graphics.newImage("flower.png")
	
	flowers = {}
for i=0,4 do
	flower = {}
	flower.nutrition = 10
	flower.clone = 0
	flower.chlorophyll = 0
	flower.width = flowergraphic:getWidth()
	flower.height = flowergraphic:getHeight()
	flower.x = i * (flower.width + 30) + 30
	flower.y = flower.height + 20
	flowerx = 0
	flowery = 0
	table.insert(flowers, flower)
end

-- schaf

	sheepgraphic = love.graphics.newImage("sheep.png")
	
	sheeps = {}
for i=0,4 do
	sheep = {}
	sheep.nutrition = 10
	sheep.width = sheepgraphic:getWidth()
	sheep.height = sheepgraphic:getHeight()
	sheep.x = i * (sheep.width + 10) + 10
	sheep.y = sheep.height + 10
	table.insert(sheeps, sheep)
end

-- our tiles
   tile = {}
   for i=0,3 do -- change 3 to the number of tile images minus 1.
      tile[i] = love.graphics.newImage( "tile"..i..".bmp" )
   end
   
   love.graphics.setFont(12)
   
   
   map={
   --well, a lot of numbers making a map, edited this out.
   { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
}
end

function love.update(dt)

mouse_x = love.mouse.getX()
mouse_y = love.mouse.getY()

-- sun for flowers

	for i,v in ipairs(flowers) do
	flower.chlorophyll = flower.chlorophyll + dt*10
		if v.chlorophyll > 100	then
	
		v.clone = 1
	
		end
	
	end

	
end

function growflower()


-- grow flower patches
	
	for ii,vv in ipairs(flowers) do
	
		if vv.clone = 1	then
		
		vv.clone = 0
		vv.chlorophyll = 0
		flowerx = vv.x
		flowery = vv.y
		
		local flower = {}
		vv.x = flowerx + 33
		vv.y = flowery
		table.insert(flowers, flower)
	
		
	
		end
	
	end


end

function draw_map()
   for y=1, map_display_h do
      for x=1, map_display_w do                                                        
         love.graphics.draw(
            tile[map[y+map_y][x+map_x]],
            (x*tile_w)+map_offset_x,
            (y*tile_h)+map_offset_y )
      end
   end
end

function love.draw()
draw_map()



for i,v in ipairs(flowers) do
	love.graphics.draw(flowergraphic, v.x, v.y)
end

for i,v in ipairs(sheeps) do
	love.graphics.draw(sheepgraphic, v.x, v.y)
end

end

Thanks in advance.

Interesting game, but I noticed one problem in your code, which is causing the problem, which is that LÖVE doesn't accept .bmp files.

LÖVE doesn't accept .bmp files.

That's not true, LÖVE can load all of the image formats on the left here: http://openil.sourceforge.net/features.php , although in the future that will probably change.

[ejmr]

Could you please post a '*.love' file with the images and everything else? That is a useful thing to do when asking for help, as it makes it easier for people to run your code, etc.

I thought it did.

Interesting game

Thank you, i want to add an avatar later that can do sandboxy stuff like placing fences, digging up flowers, killing sheep, maybe wolves... Playing with ecology, basically.

Oh, and if it didn't load *.bmp files, i would have run into problems way earlier, that is not the issue. But thank you, it would have been great if it was.

There's the file.

Code: Select all

if vv.clone = 1 then

Common mistake, but you need to use '==' here for equality test. You are accidentally using the assignment operator.

Also this is an error:

Code: Select all

love.graphics.setFont(12)

LÖVE 0.8.0 no longer supports that form of the function.

http://love2d.org/wiki/love.graphics.setFont

[davisdude]

But you can get the font at the beginning registering 'font' (or whatever) as love.graphics.setNewFont()

Code: Select all

local font = love.graphics.setNewFont()
love.graphics.setFont( font, 12 )

[slime]

https://www.love2d.org/wiki/ImageFormat

That list is for image formats LÖVE can save to, not necessarily load from. The list of formats LÖVE 0.8.0 can load from is on the left here: http://openil.sourceforge.net/features.php

Ah ok. Thanks for the link and clarification.

Yeah, totally forgot about that one. Now it works better.

The font isn't a problem right now, because i haven't updates in a while. Thanks though, because that would have caused me trouble when i get around doing that.

Now it crashes, it seems, when it tries to spawn the second flower.

By the way, where should i put that, is it right to have this in the love.update function?

Code: Select all

-- grow flower patches
	
	for ii,vv in ipairs(flowers) do
	
		if vv.clone == 1	then
		
		vv.clone = 0
		vv.chlorophyll = 0
		flowerx = vv.x
		flowery = vv.y
		
		local flower = {}
		flower.x = flowerx + 33
		flower.y = flowery
		table.insert(flowers, flower)
	
		
	
		end
	
	end
