### Screen Shake effect

I am trying to implement a screen shake effect that occurs each time an enemy is killed in my game, however I can't figure out for the life of me how to do so. Can anyone help me out here? Been stuck for a day or two now trying to get this working. Thanks

There is an example in the documentation of hump. If you don't want to use hump, this should work (untested, and should be adapted for use in your game):

Code: Select all

local t, shakeDuration, shakeMagnitude = 0, -1, 0
function startShake(duration, magnitude)
t, shakeDuration, shakeMagnitude = 0, duration or 1, magnitude or 5
end

function love.update(dt)
if t < shakeDuration then
t = t + dt
end
end

function love.draw()
if t < shakeDuration then
local dx = love.math.random(-shakeMagnitude, shakeMagnitude)
local dy = love.math.random(-shakeMagnitude, shakeMagnitude)
love.graphics.translate(dx, dy)
end
end

Just what I was looking for, thanks!

Nothing changed in the 5 years since the last post to make it not work, a quick look at the wiki articles about the used functions would also make it obvious... also please don't necro threads in the future.
