Module box2d_rs::b2_settings

Constants

B2_AABB_EXTENSION	This is used to fatten AABBs in the dynamic tree. This allows proxies to move by a small amount without triggering a tree adjustment. This is in meters.
B2_AABB_MULTIPLIER	This is used to fatten AABBs in the dynamic tree. This is used to predict the future position based on the current displacement. This is a dimensionless multiplier.
B2_ANGULAR_SLEEP_TOLERANCE	A body cannot sleep if its angular velocity is above this tolerance.
B2_ANGULAR_SLOP	A small angle used as a collision and constraint tolerance. Usually it is chosen to be numerically significant, but visually insignificant.
B2_BAUMGARTE	This scale factor controls how fast overlap is resolved. Ideally this would be 1 so that overlap is removed in one time step. However using values close to 1 often lead to overshoot.
B2_DEBUG
B2_EPSILON
B2_LINEAR_SLEEP_TOLERANCE	A body cannot sleep if its linear velocity is above this tolerance.
B2_LINEAR_SLOP	A small length used as a collision and constraint tolerance. Usually it is chosen to be numerically significant, but visually insignificant.
B2_MAX_ANGULAR_CORRECTION	The maximum angular position correction used when solving constraints. This helps to prevent overshoot.
B2_MAX_FLOAT
B2_MAX_LINEAR_CORRECTION	The maximum linear position correction used when solving constraints. This helps to prevent overshoot.
B2_MAX_MANIFOLD_POINTS	The maximum number of contact points between two convex shapes. Do not change this value.
B2_MAX_POLYGON_VERTICES	The maximum number of vertices on a convex polygon. You cannot increase this too much because b2BlockAllocator has a maximum object size.
B2_MAX_ROTATION	The maximum angular velocity of a body. This limit is very large and is used to prevent numerical problems. You shouldn't need to adjust this.
B2_MAX_ROTATION_SQUARED
B2_MAX_SUB_STEPS	Maximum number of sub-steps per contact in continuous physics simulation.
B2_MAX_TOICONTACTS	Maximum number of contacts to be handled to solve a TOI impact.
B2_MAX_TRANSLATION	The maximum linear velocity of a body. This limit is very large and is used to prevent numerical problems. You shouldn't need to adjust this.
B2_MAX_TRANSLATION_SQUARED
B2_PI
B2_POLYGON_RADIUS	The radius of the polygon/edge shape skin. This should not be modified. Making this smaller means polygons will have an insufficient buffer for continuous collision. Making it larger may create artifacts for vertex collision.
B2_TIME_TO_SLEEP	The time that a body must be still before it will go to sleep.
B2_TOI_BAUMGARTE
B2_VELOCITY_THRESHOLD	A velocity threshold for elastic collisions. Any collision with a relative linear velocity below this threshold will be treated as inelastic.
