Is there any speed limit at object velocity?

Getting Started Newbie Questions
#1

as title,

even I set the linear velocity to extremely high , It looks same to near 2000

Is there any way to increase the velocity of object?

#2

Once you pass FPS * Pixel Width (or height)  it doesn’t really matter.  The object will zip off the screen in one frame.  

Can you please give us an idea of the effect you’re trying to achieve?

Hi again.  I do want to help, so let me know what you want this to look like and I’ll try to throw together a sample.

#4

I want to move a object at faster speed(in physics),but it still seems too slow when I set linear velocity of object to high value

thanks for your answers and sorry for no reply in time

box2d has an internal velocity limit of 2 units per time step, so 120m/s at 60fps w 30ppm, which is typically plenty.

but if not, then there are two ways to get around that limit:

  1. adjust the units, see physics.setScale()

  2. adjust the time step, see physics.setTimeStep()

(or a combination of the two)

thank you davebollinger!

They are really solve my problem!
