Camera Shake? / Collisions / Enemies...

[Ryne]

Hi guys. Here is a screenshot of what Ive been working on for the last few days. I'm wondering if I could create a "Camera Shake" effect for explosions such as grenades or mines. I was thinking that I would actually have to create a "camera" somehow that I could actually "shake" unless there is an easier way to achieve the desired effect?

Thanks guys!

You probably want to play with love.graphics.translate and love.graphics.rotate.

That looks so very, very good.

Looks great!

And such an effect is easily done with translate, as bartbes said. I use it in Space as a sign you're too close to a black hole. I think I used something like:

Code: Select all

love.graphics.translate(math.random(horiz_amplitude*2)-horiz_amplitude, math.random(vert_amplitude*2)-vert_amplitude)

If you don't want the UI to shake as well, use something like:

Code: Select all

love.graphics.push()
love.graphics.translate(math.random(horiz_amplitude*2)-horiz_amplitude, math.random(vert_amplitude*2)-vert_amplitude)
-- draw game stuff here
love.graphics.pop()
-- draw UI things here

Doing something like that would look really bad if you were doing several pixels. Every single frame. It'd look like a big blur.

Actually, not really. It works pretty well in Space, check it out. (Or fork me, whatever.)

Can has video?

[Robin]

Can has LÖVE. I somehow doubt that a screencast of camera shaking effects will be very interesting.

Thanks for the comments guys! I'll try this code when I get home and try to get a demo up sometime this week.

Also, for those who were curious of the random white circle, it's the cursor for the game.

Looks fun. *waits for download*
