iAgent::testCollisionTo()

Description

Tests whether the agent can move along a line to a specified position.

Syntax

bool testCollisionTo(const iCollisionContext* context, const cPosition& newPosition) const;

Parameters

	context		The state of dynamic collision that will apply for this query. An empty context can be specified by passing a value of zero for this argument. Note that the agent is not considered to obstruct itself even if included in this context.
	newPosition		The position for the end of the query line. This position must be a valid position on the agent's mesh.

Requirements

Requires that the agent is moveable and that collision preprocess has been generated on the agent's mesh for the agent's collision shape. (But see also Performing Collision Queries without Preprocess.)

Return Value

true if the line to the specified position is obstructed, otherwise false.

Remarks

This method tests collision for a line to a fully specified target position.
In many situations the 'cell' at the target position is not known. In this case, use iAgent::testCollisionTo_XY().
