Doodads like Trees on Jungle tileset provide a chance to dodge incoming attacks to units around the tree.

Looks like that map is taking advantage of low-high ground, which has a 53.125% hit chance Chance to Hit Guide

Nah, I just tested it. I tried to use that silly flag before, it never does anything.

In the map, from left to right, the first tree is a complete doodad with the doodad's terrain tiles underneath, second tree is just the sprite with the "cover" flag checked, third tree is the sprite with the flag unchecked.
Only the first tree provides cover.

Attachments:

Oh, it appears the tiles are providing "doodad cover" (best shown by removing the sprite and putting the targeting unit on high ground), mb

No problem. Do you know how I could find out which tiles have this property and look for them? I'd like to see if the Installation tileset has any cover tiles somewhere, since all of the null tiles I tried so far didn't.

The attached version of Chkdraft isn't quite ready for release as the setpixel function is horrendous/causes lag, regardless it could be of some help

The yellow numbers are the tile values, you can set the tile value with ctrl+click, tile numbers >= 16384 should belong to doodads, though if you've tried some doodad tiles already I have my doubts other will work.

I don't see any properties of tiles that are exclusively purposed for providing cover [1][2], perhaps more investigation later.

It's my understanding that the only flags that do anything are the unit/sprite flags and the Disabled flags (but only on unit sprites).

I think it must be either 0x0001 or 0x0010 in the flags. In my (unfinished) tileset editing program I see those bits set ... In ground doodads that you can (generally) walk on the 0x0001 flag is set, in trees (and only trees) I see 0x0010 set. Except the tree part of the trees is a sprite and not part of the doodad terrain, so that doesn't make sense if it's not the sprite.

I can see all the tiles but there isn't a way to check flags is there?


Is that program published? I would just check the flags on random tiles until I found 0x0010 set, faster than testing each tile in-game anyway.

I went through every doodad in Jungle and the only tiles that have the 0x0010 flag are only the trees, and every tree has them. This does not include the rock structures you can hide behind. Also there appears to be other flags. The "ground height" flags do not appear to be that at all for doodads ...

0x0001 seems to be on ground and entirely walkable doodads (shrubs, small bones, etc.).
0x0010 seems to be for trees ... Ice and Desert have most doodads with a spite with this flag (cactus/trees, shack doodads). No Installation, Space or Twilight doodad has this flag.
0x0100 seems to be on most cover doodads (not signs in badlands or a few doodads in jungle, such as the tall cylindrical ruins doodad), and large doodads.
0x0200 seems to be on medium ground doodads.
0x0400 seems to be on high ground doodads. These two flags are probably not used ... The minitiles, as discussed earlier, have the flags for ground height. Cliff doodads facing south have the height of the higher ground, cliff doodads facing north have the height of the lower ground, and ramps have the height of the lower ground (except on Brood War tilesets).

Tiles that have cover in the map do not have irregular flags. They only have the 0x0001 flag, which no cover doodad has.
Additionally, no minitile in any tileset has an unknown flag.

Eh, doesn't look good for cover in Installation then, maybe I'll mod it sometime, I always wanted Installation to be fully playable in melee style (buildable, creep spreads, cover doodads)
