Slow moving box2d bullets

[carterza]

I'm spawning bullets in my game and they're moving extremely slow - http://i.giphy.com/3o7TKVX84bd9LrBykU.gif

In the gif, the radius of the circle is increase so you can see the debug boxes, but if I decrease it to like .009, it still moves way way too slow.

Here's the code I'm using to spawn the bodies and move them, also included my physics system initialization code -

The floor tiles under the bullets are NOT physics bodies, so there should be no interaction between them and the bullets. Why are these things moving so slow?

Thanks!

Box2d has a speed limit. Since your circles have radius of one, and are like one pixel on screen, you are probably hitting it.

I divided my viewport width and height by 24 since that's the size in pixels of one tile in my game.

If I'm hitting the speed limit - what do I need to do to make these bullets not look like they're moving at 10 feet per second? I tried increasing their radius to 10M and increasing / decreasing their density. Nothing changes. They're still slow.

You have a ratio of 1 meter per pixel in your physics world, increase this ratio like 64 pixels for 1 meter your speed will be visually increased.
