Altitude setting of aircraft under control of a tactical commander changes by itself

[meltingSnowdrift]

Steps to reproduce, as far as I understand:

1. Create a mission in which an aircraft group starts out travelling at a constant altitude of 10000 feet toward a single waypoint. Add a tactical commander that can control the aircraft.
   
2. Start the mission. As tactical commander, add two waypoints for that aircraft group. Preferably, give enough space between the group's current position and the first waypoint as well as between the first and second waypoints for altitude changes to occur gently.
   
3. Set the altitude setting of the group to approximately 4000 feet using the altitude slider.
   

 

The following will then happen.

1. It will descend to the new altitude set using the slider while proceeding toward the first waypoint and behave as expected until it passes the first waypoint.
   
2. Upon passing the first waypoint, the altitude setting of that group, as shown beside the altitude slider, will change by itself to a value near 10000 feet. This change will not be visible until the group is deselected and selected again on the command map, but its effects are immediate. This is not expected behaviour and is presumably not intended.
   
3. The aircraft group will climb toward its new altitude setting while flying toward your second waypoint as though you had changed that setting to its new value immediately after passing the first waypoint.
   

 

Attached is a track file demonstrating this issue.

Hi

 

I am not able to reproduce this one, we did have a fix for this already.

 

The AI on reaching the last set waypoint will orbit at the altitude they have been set at with the slider.

 

Which version are you using?

 

thanks

I have just reproduced the bug again. A track file and logs are attached. As far as I know, my DCS installation is up to date and there are no unofficial mods. The only installed module is combined arms.

 

In case it helps, the relevant flight is the last mission flown before quitting DCS.

No problems here.

I just ran tests starting my plane group (three SU-25T's on the Caucasus map) at 10k then ordered them down to 4k at w/p 1, and they also held it through w/p 2, then they began orbiting w/p 2 at 4k bless their little cotton socks.

I suspect we have to follow the exact sequence below to make it work-

 

Select group leader on map and click a map location to place w/p 1.

Drag slider to 4k.

Click map to place w/p 2

Right-click to lock everything.

Left-click to clear the map.

Go back to plane.

 

PS- one way of finding out your Comb Arms version is to use Settings>Misc>Theme>CA to get this pretty pic like mine, it says 1.5 at top right..:)

OK, I have been able to repeat.

 

I used the same trk/miz file in the original message.

 

To repeat

 

Start mission:

 

Set First waypoint (one from the Mission Editor) to a specific altitude. For my example i set it to 4160, i then set a second waypoint further way at 10,000, a 3rd at 8,000 and finally a fourth (and final) at 1000.

 

Once this is done, when the aircraft finishes waypoint 4 the aircraft will orbit waypoint 4 at waypoint 1's altitude of 4160.

Sorry I have had another look today with another tester, we can not reproduce this issue.

When we try the aircraft follow the waypoints, reach the desired altitudes, and when the last waypoint is reached orbit at the last waypoints altitude.
