Hello Zorg,

I read the next in attached page:

>>>Conversely, whenever it finds a number where it expects a string, Lua converts the number to a string<<<

I have the next code but it does not work.
What do I wrong?

Code:

Code: Select all

function love.draw()
	for row = 1, 4 do
	     for col = 1, 4 do
                  love.graphics.print(nr, printx, printy)
  		  love.graphics.rectangle('line',	row*40, col*40, 40, 40)
		  love.graphics.print((row-1)*4+col, row*40, col*40)
	     end
	end
end

function love.mousepressed(x, y, button, istouch)
            if button == 1 then -- Versions prior to 0.10.0 use the MouseConstant 'l'
               if (x>=20 and x<=60 and y>=20 and y<=60) then
                   nr = 99
              end
              printx = x
              printy = y
           end
end

I'm not sure which variable is giving you an error, but you could try the function tostring.

Hello Davisdude,

Now I have the next code but it still does not work.
Please send me a sample.

Code:

function love.draw()
for row = 1, 4 do
for col = 1, 4 do
love.graphics.print(str, printx, printy)
love.graphics.rectangle('line', row*40, col*40, 40, 40)
love.graphics.print((row-1)*4+col, row*40, col*40)
end
end
end

function love.mousepressed(x, y, button, istouch)
if button == 1 then -- Versions prior to 0.10.0 use the MouseConstant 'l'
printx = x
printy = y
if (x>=20 and x<=60 and y>=20 and y<=60) then
nr = 99
str=tostring(nr)
end
end
end

Hello Davisdude,

Now I have the next code and it works properly.
Thank you very much for your help.

Code:

Code: Select all

function love.load()
	       love.graphics.setNewFont(30)
         button = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "---", "Scramble", "Reset"}
end

function reset()
         love.graphics.clear()
         button = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, "---", "Scramble", "Reset"}
         for row = 1, 4 do
		         for col = 1, 4 do 
                 item = (row-1)*4+col
                 love.graphics.print(tostring(button[item]), col*40, row*40)
  		           love.graphics.rectangle('line',	col*40, row*40, 40, 40)
		         end
         end

When program crashes, you are given an error screen (error text also dumped into the terminal). It points to an exact location where the error occurred, and also gives exact reason why. Try using that information to trace down to the source of the problem. Often enough, problem is very simple to resolve, saving you time waiting on others to assist you with this.
