newDistanceField3D()

DistanceField3D * eve::physics::Physics::newDistanceField3D	(	int	width,
		int	height,
		int	depth,
		float	cellSize,
		float	originX = 0.f,
		float	originY = 0.f,
		float	originZ = 0.f,
		float	outsideDistance = 1e6f
	)

Create a regular 3D signed-distance grid for map collision queries.

返回

Owning nullable field pointer transferred to the caller. @ownership The caller owns the returned field and must delete it after use. @lifetime Valid until caller destruction; it is not retained by Physics. @thread Create and use on the owning physics thread. @reentrancy The factory invokes no callbacks.

在文件 Physics.cpp 第 49 行定义.

引用了 depth, height , 以及 width.

newFluid2D()

Fluid2D * eve::physics::Physics::newFluid2D

(

int

capacity = 512

)

Creates an interactive 2D particle fluid in pixel space.

参数

capacity

maximum number of particles (>= 1)

返回

Owning nullable fluid pointer transferred to the caller. @ownership The caller owns the returned fluid and must delete it after use. @lifetime Valid until caller destruction; it is not retained by Physics. @thread Create and use on the owning physics thread. @reentrancy The factory invokes no callbacks.

在文件 Physics.cpp 第 67 行定义.

引用了 capacity.

newSoftBody3D()

SoftBody3D * eve::physics::Physics::newSoftBody3D	(	int	cols,
		int	rows,
		int	layers,
		float	spacing,
		float	originX,
		float	originY,
		float	originZ
	)

Compatibility factory for a volumetric shape-matching soft body.

The canonical C++ creation API is SoftBody3D::create(), which returns a checked owning unique_ptr. This adapter exists for the script binding, whose VM assumes ownership of the returned wrapper.

返回

Owning pointer transferred to the script VM/caller. @ownership The caller owns the returned object and must destroy it. @lifetime Valid until caller destruction; a borrowed World3D must be cleared first. @thread Create and use on the owning simulation thread. @reentrancy No callbacks are invoked.

异常

eve::Exception

when dimensions or coordinates are invalid.

在文件 Physics.cpp 第 56 行定义.

引用了 cols, eve::physics::SoftBody3D::create(), created, rows , 以及 spacing.

newSoftBody3DRenderer()

SoftBody3DRenderer * eve::physics::Physics::newSoftBody3DRenderer

(

SoftBody3D *

body

)

Create a presentation satellite observing a soft-body runtime.

参数

body	Borrowed nullable runtime; clear it on the renderer before destroying the body.

返回

Owning renderer transferred to the script VM/caller. @ownership The caller owns the renderer; it never owns body or Graphics. @thread Create and use on the owning render thread.

在文件 Physics.cpp 第 63 行定义.

引用了 body.

newWorld()

World * eve::physics::Physics::newWorld	(	float	gravityX,
		float	gravityY,
		bool	sleep = true
	)

Create a 2D Box2D physics world.

参数

gravityX	gravity X in pixels/s²
gravityY	gravity Y in pixels/s²
sleep	allow sleeping bodies

返回

Owning nullable world pointer; the caller is responsible for deleting the wrapper. @ownership Ownership transfers to the caller; the Physics module does not retain the wrapper. @lifetime Valid until caller destruction; call World::destroy() before releasing backend resources. @thread Create and use on the owning physics thread. @reentrancy The factory invokes no callbacks; do not re-enter physics mutation while using the result.

在文件 Physics.cpp 第 41 行定义.

newWorld3D()

World3D * eve::physics::Physics::newWorld3D	(	float	gravityX,
		float	gravityY,
		float	gravityZ,
		bool	sleep = true
	)

Create a 3D Box3D physics world. Coordinates are meters (Box3D native); +Y is up by convention.

参数

gravityX	gravity X in m/s²
gravityY	gravity Y in m/s²
gravityZ	gravity Z in m/s²
sleep	allow sleeping bodies

返回

Owning nullable world pointer; the caller is responsible for deleting the wrapper. @ownership Ownership transfers to the caller; the Physics module does not retain the wrapper. @lifetime Valid until caller destruction; call World3D::destroy() before releasing backend resources. @thread Create and use on the owning physics thread. @reentrancy The factory invokes no callbacks; do not re-enter physics mutation while using the result.
