Returns

Returns false if there is no valid solution or the valid solutions are blocked. Returns true otherwise.

Parameters

Parameter

Description

TossVelocity

(output) Result launch velocity.

StartLocation

Intended launch location

EndLocation

Desired landing location

LaunchSpeed

Desired launch speed

OverrideGravityZ

Optional gravity override. 0 means "do not override".

TraceOption

Controls whether or not to validate a clear path by tracing along the calculated arc

CollisionRadius

Radius of the projectile (assumed spherical), used when tracing

bFavorHighArc

If true and there are 2 valid solutions, will return the higher arc. If false, will favor the lower arc.

bDrawDebug

When true, a debug arc is drawn (red for an invalid arc, green for a valid arc)
