angleThe angle of the box (in degrees).
directionA vector representing the direction of the box.
resultsArreglo para recibir resultados.
distanceThe maximum distance over which to cast the box.
layerMaskFilter to detect Colliders only on certain layers.
minDepthOnly include objects with a Z coordinate (depth) greater than or equal to this value.
maxDepthOnly include objects with a Z coordinate (depth) less than or equal to this value.

Valor de retorno

int Returns the number of results placed in the results array.

Descripción

Casts a box into the Scene, returning colliders that contact with it into the provided results array.

This function is similar to the BoxCastAll function except that the results are returned in the supplied array. The integer return value is the number of objects that intersect the box (possibly zero) but the results array will not be resized if it doesn't contain enough elements to report all the results. The significance of this is that no memory is allocated for the results and so garbage collection performance is improved when performed frequently.

The returned RaycastHit2D returns both the point and normal of the contact where the box would touch the collider. It also returns the centroid where the box would be positioned for it to contact at that point.
