Problem with PickupObject crashing to desktop

Just doing some testing and in a simple non-mutation mode map, I'm having issues with PickupObject.

As a simple test, I have this code.

// test model is models/props_misc/tea_pot-1.mdl local sv = Entities.FindByName(null,"!nick"); local item = Entities.FindByName(null,"pickup"); printl(sv+" picking up "+item); PickupObject(sv,item);

Now for the prop_physics and prop_physics_multiplayer I've tried, (unchecking generate output on +USE as the wiki suggests), this simple causes a crash to desktop.

If I mark the flag to Force Serverside, the script executes and nothing happens.

If I set it to a normal carryable like Gnome, it doesn't crash either way, but still won't pick it up.

Is there something I'm missing here?

Apparently you also need g_ModeScript::CanPickupObject(object) set up right. I only got it working after overriding CanPickupObject after the mode script has been run (setting it to run on an entity in hammer does not work). Also it only works if there is an actual mode script file, I created one for coop, and it worked.

Thanks for the info. I tried just adding it to g_ModeScript and g_MapScript with no luck. Really too bad. This should work for custom campaigns as well.

I did some further testing. It seems to only hook the CanPickupObject function if it's there when the mode script first loads. Afterwards it's possible to replace the contents with anything you want. Putting a placeholder function in coop.nut works for me, but it doesn't feel very portable.

I really wanted to use this feature in my campaign, so I hope Valve improves it.

And even in mutation mode, it only seems to work with certain things, Gnome yes, teakettle no. Am I missing something?

It probably won't work on props set up as client side or debris, since the vscripts are run on the server. Not sure if the "force serverside" option helps though. At least it's possible to pick up big things, like cars and dumpsters.

That's what I figured, I'm sure it's user error.

Forcing serverside won't network the changes to the entity state. Did you set the ent data for your model before compiling the QC?

I made a little test mutation that allows you to pull objects toward you, and then throw them, WITH YOUR MIND!
