Problem With Co-Op

SteamsDev · Soldier **Joined**: 12 Mar 2017

Hello,
I am trying to play my own custom co-op mission via LAN. I thought I had done everything right, but when I launch the game I get this error message:

"Exception has been thrown by the target of an invocation."

Can someone help me fix this problem?

Go to your DTA directory, then to the "Client\ErrorLogs\" sub-directory. Find the client crash log there and upload it to this topic.

Is your "co-op mission" a regular multiplayer map or an actual co-op mission? If it's an actual co-op mission, have you added it to MPMaps.ini correctly, for both the game host and other players?

Also, which PC gets the error message? The game host, the clients or both?

It is an actual co-op mission, and I believe I added it ot MPMaps.ini correctly. The only thing that isn't correct is starting locations, which I do need help on. Picture is attached.

Clients. The client crashes after the error message is given.

In the game lobby, what are your Starting Credits and Tech Level options set to before the game is started (on the client PCs)?

Can you select something as the tech level as the game host?

If not, could you post the map's code in MPMaps.ini here?

Got it fixed. I just had to change cmbTechLevel in MPMaps.ini to get it to work. Problems left have to do with the map, which I can resolve myself.

Thank you for your help!

Still trying to solve problems with my co-op map. I got past the "Creating theories on likely enemy plan" part by editing MPMaps.ini for the 3 AIs that are in this map, but now I can't get past "Deploying forces to combat zone" part, which I feel like means that something's wrong on the map that it crashes on checking. I also haven't fixed the waypoints problem, mainly because I have no idea how to do it.

Below is a ZIP file containing the map, its preview, and the MPMaps.ini file. I think that's all that is needed.

EDIT: Oh yes, and the EXCEPT file is also being uploaded. I think that has something to do with it.

There are 2 causes for the crash:

You added houses to the map, which shouldn't be done for any multiplayer maps. So to fix this issue, simply delete all houses in the map editor or open the map with a text editor and just delete the [Houses] section.
You made all triggers belong to the Spawn-houses. While Spawn-houses should never own triggers in the first place, triggers on multiplayer maps in general should really only be owned by the Neutral (or Special) house in order to avoid crashes (the map will crash if any other house owns a trigger and the game is started while no players selected that house).
To fix this issue, either just change the specified House of all triggers to Neutral in the map editor or open the map with a text editor and in the [Triggers] section, replace every instance of "=Spawn#" (# being any number) with "=Neutral".
