Hi, I am having another issue with Dark Physics, I have specified the gravity for an object (In this case the player, a sphere), but the problem is, I either fall down in super speed, or in slow motion. I I for example, set gravity to 1, I fall in super speed, and if I set gravity to 0.9 I fall in slow motion, even 0.99999 makes me fall in slow motion.

Any suggestion on how to fix this? Please answer

the standard is -9.8, and a mass of a normal object is 10,000. does that help.

As HowDo has pointed out, the default is -9.8 you need to have the value a minus. In my PhysX demo because I had to set gravity to -30 odd for it to look right, well, it's still a bit like the boulders are falling in slow motion or they are on the moon lol

Hmmm...It falls in hyperspeed when I set gravity to -9.8

My code for clarification:



I'm fairly new to D Phy so if you find any other issue except gravity, please not that as well, thanks.

The command Phy set rigid body gravity instructs the object whether it should be affected by gravity or not. It is not used to assign individual gravity to objects. There is a minor bug that although you set gravity interaction to zero (in your case the 0.999 is taken as zero), the object still moves slightly down.

As you mention in the thread title, your problem relates to the zero sync rate. By doing so, you're allowing the physics simulation to update constantly and as fast as possible. If you change the rate to 60, you'll notice that they will move smoothly.

Theory is when you know something, but it doesn't work. Practice is when something works, but you don't know why.
Programmers combine theory and practice: Nothing works and they don't know why.

I`v moded your code, just to help a beginner.
