why am i getting this error?

[RocketSocketGames]

im getting a strange error when i try to make a variables' value go up. it says

Code: Select all

Error

Syntax error: main.lua:6: '=' expected near '+'



Traceback

[C]: at 0x52f6d550
[C]: in function 'require'
[C]: in function 'xpcall'
[C]: in function 'xpcall'

but when i actually put it near '+' this happens!

Code: Select all

Error

Syntax error: main.lua:6: unexpected symbol near '+'



Traceback

[C]: at 0x52f6d550
[C]: in function 'require'
[C]: in function 'xpcall'
[C]: in function 'xpcall'

heres the code im using:

Code: Select all

count = 0
function love.draw()
love.graphics.print(count, 400, 150)
end
function love.keyboard.isDown(space)
count + 1
end

Code: Select all

function love.keyboard.isDown(space)
	count + 1
end

https://love2d.org/wiki/love.keypressed

Code: Select all

function love.keypressed( key, scancode, isrepeat )
	if scancode == "space" then
		count = count + 1
	end
end

The isDown must be called from update (or draw).

[RocketSocketGames]

Code: Select all

function love.keyboard.keypressed( key, scancode, isrepeat )
	if scancode == "space" then
		count = count + 1
	end
end

that doesnt work. when i press space. the printed number doesnt update.

edit: and heck, when i reuse the code on a different project, it doesnt even work at all!

You misspelled little ("love.keypressed" instead "love.keyboard.keypressed"):

Code: Select all

count = 0
function love.draw()
  love.graphics.print(count, 400, 150)
end

function love.keypressed( key, scancode, isrepeat )
	if scancode == "space" then
		count = count + 1
	end
end

You misspelled little

thats the most random thing to say. because none of us said "little"

[GVovkiv]

also

Code: Select all

count = 0
function love.draw()
love.graphics.print(count, 400, 150)
end

function love.keyboard.isDown(space) -- isDown needs string as argument, but you send it variable space (which in that case == nil), not string "space"
count + 1 -- lua doesn't support "=+", "=-", etc; only value = value + 1
end -- also, "love.keyboard.isDown()" it's not callback, it should be used in conditions:

love.update = function()
   if love.keyboard.isDown("space") then
   *something*
   end
end

ok, cool
just use "love.keypressed()" instead of "love.keyboard.keypressed()" ok?

Not everyone's first language is English.

I think GVovkiv meant "You made a little misspelling".
