ProjectionInfo

Description

A structure used to represent projection information from a point to a line segment, including whether the projection point is on the segment, the coordinates of the projection point on the segment, etc.

How to Use

// Define the start and end points of the segment
Vector segmentStart = ObjectManager::Player()->Position();
Vector segmentEnd = segmentStart.Extend(targetPosition, 500.f);

// Calculate the projection of the target point to the segment
Vector pointToProject = enemy->Position();
ProjectionInfo projection = pointToProject.ProjectOn(segmentStart, segmentEnd);

// Use the projection result
if (projection.IsOnSegment)
{
    // The projection point is on the segment
    Vector projectedPoint = projection.SegmentPoint;
    
    // Calculate the perpendicular distance from the target point to the segment
    float distanceToLine = pointToProject.Distance(projectedPoint);
    
    // Determine if the target is within skill range
    if (distanceToLine <= 60.f) // Skill width is 120, radius is 60
    {
        // The target is within the linear skill's area of effect
        ObjectManager::Player()->CastSpell(eSpellSlot::Q, segmentEnd);
    }
    
    // Calculate the relative position of the projection point on the segment
    float projectionDistance = segmentStart.Distance(projectedPoint);
    float segmentLength = segmentStart.Distance(segmentEnd);
    float projectionPercentage = projectionDistance / segmentLength;
    
    // Make decisions based on projection position
    if (projectionPercentage > 0.7f)
    {
        // Target is close to the end of the segment
    }
}
else
{
    // The projection point is not on the segment, it might be on the extended line
    Vector linePoint = projection.LinePoint;
    
    // May need to adjust skill direction to hit the target
}
