Question (urgent!) - a simple 2D game

[ngrmile]

Hi,

I've just started learning to create 2D games with LOVE, and I'm kind of stuck with this one little problem.
If you run this and press directional keys, the cursor moves ridiculously fast.
It's because I'm moving the unit 35 pixels at a time, but I would like it to move much slowly.
In other words, I would like the system to recognize key input less often, if that's at all possible.
Any suggestions? Please help >_<;

Here's the code for your convenience:
(you can simple copy & paste the whole thing and it will run fine)

--main.lua

-- LOAD --

function love.load()

img = {

unit1 = love.graphics.newImage("unit1.png"),

}

units = {

{ -- cursor --

pos = { 0 *35+1, 14 *35+1 }, -- coordinates
--speed = 0.1, -- movement speed
moveDir = { 0, 0 }, -- movement direction

},

{ -- Unit #1 --

pos = { 7 *35+1, 8 *35+1 }, -- coordinates
speed = 70, -- movement speed
moveDir = { 0, 0 }, -- movement direction

},

{ -- Unit #2 --


pos = { 10 *35+1, 2 *35+1 }, -- coordinates
speed = 70, -- movement speed
moveDir = { 0, 0 }, -- movement direction

},
}

love.graphics.setBackgroundColor(200,230,230) -- BG color

end

-- UPDATE --

function love.update(dt)

units[1].pos = {

units[1].pos[1] + (units[1].moveDir[1] * 35),
units[1].pos[2] + (units[1].moveDir[2] * 35)

}

end

-- DRAW --

function love.draw(dt)

for i=35, 15 *35, 35 do
--local tmp = love.graphics.setColor(0,0,0)
love.graphics.line(i, 0, i, 15 *35)
love.graphics.line(0, i, 15 *35, i)
end

love.graphics.draw(img.unit1, units[1].pos[1], units[1].pos[2])
love.graphics.draw(img.unit1, units[2].pos[1], units[2].pos[2])
love.graphics.draw(img.unit1, units[3].pos[1], units[3].pos[2])

end

-- KEY PRESSED / RELEASED --

function love.keypressed(key, isrepeat)

if key == "up" then
units[1].moveDir[2] = -1
elseif key == "down" then
units[1].moveDir[2] = 1
elseif key == "right" then
units[1].moveDir[1] = 1
elseif key == "left" then
units[1].moveDir[1] = -1
elseif key == "escape" then
love.event.quit()
end

end

function love.keyreleased(key, isrepeat)

if key == "up" then
units[1].moveDir[2] = 0
elseif key == "down" then
units[1].moveDir[2] = 0
elseif key == "right" then
units[1].moveDir[1] = 0
elseif key == "left" then
units[1].moveDir[1] = 0
end

end

Use dt.

Code: Select all

function love.update(dt)

  units[1].pos = {

  units[1].pos[1] + (units[1].moveDir[1] * (35 * dt)),
  units[1].pos[2] + (units[1].moveDir[2] * (35 * dt))

  }

end
