[Solved]i want to make the enemy kill the player but it keeps giving me the error(read below)

Why are you iterating over player?

[CaptainLK]

What this for loop does is iterating over every variable in player:
A little example of what you are doing:

Code: Select all

player = {x = 200,y = 200,Speed = 400, width = 30, height = 50}
for i, v in pairs(player) do
	print(v)
end

This is what it would output:

Code: Select all

200
200
400
30
50

So if you only have a single object there is no need for a for loop

Code: Select all

function love.load()
player = {x = 200,y = 200,Speed = 400, width = 30, height = 50}
enemy = {x = 150,y = 150, speed = 1000,width = 15,height = 15}
points = {{x = 400,y = 555,width = 10,height = 10}}
pointscounter = 0


end

function love.draw()
	love.graphics.setColor(144,255,71)
	love.graphics.rectangle("fill",player.x,player.y,player.width,player.height)
	love.graphics.setColor(245, 58, 252)
	for i , v in pairs(points) do
		love.graphics.rectangle("fill",v.x,v.y,10,10)
	end
	love.graphics.setColor(144,255,71)
	love.graphics.setColor(255,255,255)
	love.graphics.print(pointscounter,0,0,0,1.5,1.5)
	if pointscounter == 50 then
		love.graphics.setColor(255,255,255)
		love.graphics.print("You Win", 350, 300,0,1.5,1.5)
	end
	love.graphics.setColor(255,0,0)
	love.graphics.rectangle("fill",enemy.x,enemy.y,15,15)
end

function love.update( dt )
	if love.keyboard.isDown("d") and player.x + player.width < 800 then
		player.x = player.x + player.Speed * dt
	end
	if love.keyboard.isDown("a") and player.x > 0 then
		player.x = player.x - player.Speed * dt
	end
	if love.keyboard.isDown("w") and player.y > 0 then
		player.y = player.y - player.Speed * dt
	end
	if love.keyboard.isDown("s") and player.y + player.height < 600 then
		player.y = player.y + player.Speed * dt
	end
	
	dx = (player.x - enemy.x) * (enemy.speed * dt)
	dy = (player.y - enemy.y) * (enemy.speed * dt)
	enemy.x = enemy.x + (dx * dt)
	enemy.y = enemy.y + (dy * dt)

		if CheckCollision(enemy,player) then
			print("Got Hit")
		end
	for i,v in ipairs(points) do
	if CheckCollision(player,v) then
	pointscounter = pointscounter + 1
	v.delete = true
	local newpoint = {x = math.random(690), y = math.random(490)}
	table.insert(points,newpoint)
	end
	end

	for x = #points,1,-1 do 
		if points[x].delete then
			table.remove(points, x)
		end
	end
end

function love.keypressed ( key )
	if key == "escape" then
	love.event.quit()
	end
end

function CheckCollision(a,b)
  if a.x > b.x + b.width or b.x > a.x + a.width then
    return false
  end
  if a.y > b.y + b.height or b.y > a.y + a.height then
    return false
  end
  return true

Here is the working code, I fixed some other errors and changed your collision detection

[NathanGaming2005]

i got it the new code detects if the enemy touches the player
like

Code: Select all

for I, v in pairs(enemies) do
 if aabb(player.x,player.y,player.width,player.height) then
 player_die()
end



end

function player_die()
game_load()
player.x = 50
player.y = 50
player.speed = 400
end

[NotARaptor]

I'd probably add a "break" after the player_die() call - if two or more enemies touch the player in the same frame, game_load() will be called that many times, and you probably don't want that.
