Ad vs Set in physics movement

For questions about using Classic.

Post » Tue Mar 25, 2008 3:02 pm

What's the difference between ad and set force/torque? I thought set torque to 0 would stop the sprite from rotating emmediately, and set force 0 would stop it from moving. Ad and set seems to do the same thing right now.

If you did

+ Start of layout
: Add force 5
: Add force 5

the total force added is 10.

If you did

+ Start of layout
: Set force 5
: Set force 5

the total force applied to the object is still 5. Simple, 'add' is for cumulative forces, and 'set' is for overall.

Also, to stop something rotating use Set Angular Velocity.

But set force 0 don't stop the object from moving... Why?

Now that you mention it, that is strange.

Im afraid that Add and Set are the same in Construct.

Edit: Yeah i was trying to make a little Solar System and it failed becouse the Gravity force was always adding not setting... even when i give "Set" function.
