and what's the error?

whiteviperxOP•2y ago

'-' cannot be applied to operands of type 'Transform[]' and 'int'

ero•2y ago

so there you go

whiteviperxOP•2y ago

yes but how do I solve it?

ero•2y ago

don't apply '-' on an operand of type 'Transform[]'

whiteviperxOP•2y ago

I want the code to look somethings like this but this didnt work either

    
    private void GetNextWaypoint()
        {
        if(wavepointIndex >= Waypoints.points.Length - 1)
            {
            EndPath();
            return;
            }

    
    private void GetNextWaypoint()
        {
        if(wavepointIndex >= Waypoints.points.Length - 1)
            {
            EndPath();
            return;
            }

ero•2y ago

and why didn't it work?

whiteviperxOP•2y ago

causes problems in the waypoint scripts I think i have to start over on the scripts... I'm just trying to get the enemy to follow waypoints and point in the correct direct at each turn

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
