Full physics comes to CybaLOUNGE:.
How to make objects solid
Imitates real physics: gravity and friction. Makes objects act like solids. You can set the mass of an object.
Physics comes to Cybalounge
- CybaLOUNGE
- https://nonprofitvirtualworld.org/
- You can set objects to collision--that makes objects act as if solid.
- We usually call objects physical when they are set to act as if solid.
- (We people of the digital worlds)
- You can walk on physical objects and bump into them.
- You can turn on gravity in your place and set it to the level you want.
- You can set gravity to much less than earth level and make things fall slowly.
- Instructions after the break.
**********************************************
Collision cautions: the takeaways
- Physics uses computing. It can overload your computer.
- Never use collision unless you need it, as in stairs and upper floors.
- Or in physics demonstrations.
- Never set a mesh object to collision.
- Make a bounding box for it and make the box transparent
- Best set only single prims for collision.
Background
CybaLOUNGE settings for physics
Set your location to physical
- To see the location dialog, click the house button (bottom line, right side)
Location setting for physics
- True physics checked.
- Gravity set with slider.
- The setting of 25 means about 25% of earth gravity.
- Reduced gravity means that things fall more slowly
Set an object to collision
- Click the crossed tools (bottom line) to enter the construction mode.
- Click the object to select it for editing.
- Click the General tab and check the collision property
Set the object to collision
- Option: set physics properties for the object.
- You don't need to set these properties if you just want collision.
Set physics properties
(Optionally)
- Toggle collision on in the location.
- Your avatar can get stuck at collision objects.
- Toggle off to get unstuck.

Use collision efficiently
With mesh
- Decide what surfaces you need to be solid.
- Make a bounding box prim that matches the surface.
- If the surface is irregular, as usual with mesh,
- make a single simple prim that fits in front of or above the surface.
- Position the prim, then set it transparent.
