Could the black background be translucent? As it stands it's a little jarring to look at.

[Buggie]

No any point. For readability solid is best.

One interesting thing I've noticed when using MindReader with ScriptedPawns is that the Destination and Focus are sometimes given as 'QueenDest' in maps which don't have this Actor in them - it's not important (at least for me) but any idea why that should be?

DM-[NES]USZ_2022 is one of the maps where this happens.

[Buggie]

MindReader report only exists things. If it report about QueenDest, then on map present QueenDest. Use search actors for find them.
Sometimes mapper drop actors, which don't has visible representation by one or another reason. Since they not visible, mapper not notice them and release map with it.
This explain invisible redeemer ammo, invisible collide trees and invisible flames.
Same can be here.

No QueenDests in that map:

@OjitroC: what mutators do you use? Maybe one of them injects QueenDests into the map.

Can I bring you my opinions ?
Let's see...
In map's Editing process, some boys are copying assets from elsewhere from pathed maps. This will result in some references that are ONLY DESCRIBED but they don't exist in target map. I was already showing some map with supposed paths that are nowhere. VisNoReachPaths are Navigation ACTORS referenced and we can have here internal chains created in previous source map pointing to corresponding actors. When these are selected and "COPY-PASTE"-ed elsewhere in that state it's normal to return a map with GAPS pointing Actors that are nowhere - and if you ask my private public opinion, this is the first route to memory corruptions making some players to get tired of GPF crashes since these boys are not having any clue what they do.

In other hand I would like to drop an eye over that map...

@OjitroC: what mutators do you use? Maybe one of them injects QueenDests into the map.

Yes, you are right of course - I'm using MonsterSpawn and, looking at the (obfuscated) code, I see that it does indeed inject QueenDests into maps (as one would expect I suppose) - so that's cleared that up for me

[sektor2111]

So MonsterSpawn doesn't use a sanity check if internal QueenDests could spawn ? Good to know...

At the risk of derailing the thread, I'm not sure in what circumstances internal QueenDests would be spawned in a DM map? However my uninformed reading of the code suggests that MonsterSpawn only spawns QueenDests if the property/variable AllowQueensXtraTeleports is set to true - which mine is at the moment anyway. Since I don't use QUeens in MonsterSpawn, I'll turn it off and see what happens.

Had the following crash using MindReader (the first time it has crashed after extensive use)

Don't know if there is enough information there to indicate what might be the cause of the runaway loop or of the crash.

The map is a pathed version of (LAGG)MountainCity - I pathed it using PathsMaker and then it was 'cleaned up', using MapGarbage, to remove or reposition PathNodes without connections in and/or out and the pathnetwork then rebuilt (I don't normally alter PlayerStarts or InventorySpots that lack connections as I am not pathing the map for bots but for the spawning of Relics and ScriptedPawns).

I had a crash in the same map earlier related to the drawing of the Biogelm LodMesh but presumably the 2 crashes are unrelated.

Nothing out of the ordinary in the map except that a rifle and some ammo 'fell out of the world' - I use StuffSwapper with CS weapons and this happens sometimes, possibly due to the size or whatever of those weapons/ammo compared to the default UT sniper and ammo.

[Buggie]

Unfortunately in UT no way for draw line on screen. So it going with hack with fill pixel 1-by-1. Which is expensive and if there many lines, this can hit runaway limit.
Unfortunately there no much which can be done with that. But this happen not really often.

[OjitroC]

Thanks for the info. No, it doesn't happen often at all - I run MindReader all the time and use it quite a lot in-game particularly when checking out 'new' ScriptedPawns - so it's very useful and the (very) occasional crash is not a problem.

Unfortunately in UT no way for draw line on screen.

A workaround is to use a diagonal line texture ("slope 1"), and mess around with RectX and RectY below to 'rotate' it.



Here is something I imagine could work, but I haven't tested it – it does, however, have the original idea. This assumes that using a negative value for RectY in DrawRect will flip the texture upside down.

Documentation comments are Doxygen-style.
