PointsInRange
bool PointsInRange(fixed a, fixed b, fixed distance);
Are both points in distance range.
Parameters
- fixed a
First point
- fixed b
Second point
- fixed distance
Maximal distance between a and b
Return value
bool - Is the distance between both points smaller or equal than the distance.
Examples
- Example #1: Sample Usage
PointInRange(Point(0, 0), Point(1, 1), 1) // true PointInRange(Point(0, 0), Point(0, 10), 15) // false
- Example #2: Recode It
bool PointsInRange(point a, point b, fixed distance) { if (distance < 0) { return false; } return DistanceBetweenPoints(a, b) <= distance; }
- Example #3: IsPlayerWatching
// Tell if the player camera can see the unit bool IsPlayerWatching(int player, unit u) { point cameraPos = CameraGetTarget(player); point unitPos = UnitGetPosition(u); return PointsInRange(cameraPos, unitPos, 20); }
