Unable to shoot
 

One of those things which happens with really large levels. I can't shoot on some tiles for some reason, and also ammo doesn't spawn on some places, which I believe has a pattern: Top-left has most ammo, bottom-right has least. Also ammo crates won't spawn the 5 ammo events. Some crates are also missing. I removed tons of Carrot crate with ExtraEvent TNT and NumEvent 15 and replaced them with TNT +3 ammo, but that doesn't help a lot. If I'm not wrong, this has something to do with not enough memory in JJ2, and I need to remove events, but I've removed a lot and nothing's changed.

You just need to remove even more.

Best advice I ever got. :roll: Seriously though, it's almost hard to strip it of more ammo.

Like it or not, I think Jake is right. Assuming this is the level for FireSworD's contest, and assuming it's as big as you were hinting, it's the only solution I can think of for now.

As far as I know, the object limit in SP is 511. Each generator takes up two entries in the object array (one for the generator and one for the object it spawns). You can unload objects from the array by getting far enough (there's a 64*64 tile square of "active memory" surrounding the player, and any objects outside that area will be unloaded), so separating the areas from each other with thick enough walls might let you use more objects.

It's an MP level, so does that change the object limit? Also, are there actually six objects for a +15 ammo box: the box and the 5 +3 ammo objects? And double that amount for the generator?

The object limit is 2559 in MP (note that level settings won't change it, so you must test it in MP in order to get the increased object limit). Barrels and crates take up only one object from the array and the extra objects are allocated when they are destroyed (they store what they must spawn and how many of them in their object data). The generator still takes up another object as normal, though.

Also, the unloading trick won't work in MP.

Would it be ok for you to take a look at the level and suggest a solution? I'm kind of stuck with this.

I could, I have mine's layout done already ;)
