Remarks
Calculates an launch velocity for a projectile to hit a specified point. Returns false if there is no valid solution or the valid solutions are blocked. Returns true otherwise.
Parameters
| Name | 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) |
