Remarks
Returns the launch velocity needed for a projectile at rest at StartPos to land on EndPos. Assumes a medium arc (e.g. 45 deg on level ground). Projectile velocity is variable and unconstrained. Does no tracing.
Parameters
| Name | Description |
|---|---|
| OutLaunchVelocity | Returns the launch velocity required to reach the EndPos |
| StartPos | Start position of the simulation |
| EndPos | Desired end location for the simulation |
| OverrideGravityZ | Optional override of WorldGravityZ |
| ArcParam | Change height of arc between 0.0-1.0 where 0.5 is the default medium arc, 0 is up, and 1 is directly toward EndPos. |
