Detailed Description

Footprints - an approximation of the entity's shape, used for collision detection and for rendering selection outlines.

A footprint is either a circle (of some radius) or square (of some width and depth (actually it's a rectangle)), horizontally aligned, extruded to a given height.

Member Function Documentation

virtual void ICmpFootprint::GetShape ( EShape &  shape, entity_pos_t &  size0, entity_pos_t &  size1, entity_pos_t &  height  )

pure virtual

Return the shape of this footprint.

Shapes are horizontal circles or squares, extended vertically upwards to make cylinders or boxes.

Parameters

[out]	shape	either CIRCLE or SQUARE
[out]	size0	if CIRCLE then radius, else width (size in X axis)
[out]	size1	if CIRCLE then radius, else depth (size in Z axis)
[out]	height	size in Y axis

Implemented in CCmpFootprint.

CScriptVal ICmpFootprint::GetShape_wrapper

(

)

GetShape wrapper for script calls.

Returns { "type": "circle", "radius": 5.0, "height": 1.0 } or { "type": "square", "width": 5.0, "depth": 5.0, "height": 1.0 }

Definition at line 27 of file ICmpFootprint.cpp.

virtual CFixedVector3D ICmpFootprint::PickSpawnPoint ( entity_id_t  spawned )

pure virtual

Pick a sensible position to place a newly-spawned entity near this footprint, such that it won't be in an invalid (obstructed) location regardless of the spawned unit's orientation.

Returns

the X and Z coordinates of the spawn point, with Y = 0; or the special value (-1, -1, -1) if there's no space

Implemented in CCmpFootprint.
