Member Data Documentation

gravity

float nudge::GlobalData::gravity[3]

by default each body uses its own gravity (in its 'properties'), but by using the GF_USE_GLOBAL_GRAVITY flags, all the bodies share this gravity value (defaults to {0,-9.82,0})

flags

uint32_t nudge::GlobalData::flags

bit mask of GF_ flags; please do not reset it, just set or reset flags inside it (because some flags could be set by default, and other flags could be added in the future)

exclude_smoothing_graphic_transform_flags

FlagMask nudge::GlobalData::exclude_smoothing_graphic_transform_flags

bit mask of BF_ flags; default value is 0; this flag just affects body transform smoothing in two functions (calculate_graphic_transform_for_body(...) and calculate_graphic_transforms(...)); note that in any case static bodies and dynamic sleeping bodies are always not smoothed, because they are still; possible values are usually: BF_IS_DYNAMIC and/or BF_IS_KINEMATIC (both together disable transform smoothing completely)

removed_bodies

uint32_t* nudge::GlobalData::removed_bodies

[internal usage, remove_body(...)] since we can't remove bodies properly, instead we put bodies in stand-by ready to be reused (when new bodies are added) and we free their colliders; removed bodies end in this list and can be filtered out using their BF_IS_REMOVED flag

removed_bodies_count

uint32_t nudge::GlobalData::removed_bodies_count

[internal usage]

finalized_removed_bodies_count

uint32_t nudge::GlobalData::finalized_removed_bodies_count

[internal usage] finalized_removed_bodies_count<=removed_bodies_count; finalization happens at the start of the simulation_step(...) function

removed_bodies_capacity

const uint32_t nudge::GlobalData::removed_bodies_capacity

[internal usage] should be == c->MAX_NUM_BODIES
