Talk:Oni engine patches (Mac PPC)

Mac Daodan

What's the possibility of making something Daodan-like for the Mac, or placing function calls in code caves? --rossy 11:18, 10 October 2008 (CEST)

Define "code caves"; I'm not sure there's many of those, and we can't go very far with a hackish approach anyway. As for DLL-similar stuff, SFeLi said it was feasible and even relatively easy with Mach-O files: I haven't looked into that myself. --geyser 18:06, 10 October 2008 (CEST)

Code caves? There are a ton of those in the Mac executable :) Neo

Uppercase letters at the console

Issue still unsolved as of 06:39, 22 October 2008 (CEST)

Hmm, about the Shift key not being 'accessible'... I actually never noticed before that one cannot type capital letters on the command line, and if I did notice it I would have assumed the PC version was the same. So, one point and one question:

• It's not exactly true that the Shift key is not accessible or not recognized, because I can type important characters like the underscore and parentheses. It's merely that uppercase letters cannot be typed.
• Is the lack of access to uppercase letters an issue? This is total news to me, so naturally I am curious as to whether this has been a problem on the Mac side of things that I never knew about. --Iritscen 03:04, 7 October 2008 (CEST)

The PC command line has no major issues: uppercase letters can be entered both on PC and PC demo. There are occasional glitches with autocompletion and some inconsistencies with multithreading (i.e., "fork"ing may not work as expected when launched from the console). Also, the command line is not displayed properly or at all at large resolutions.

Thanks for the disambiguation about the Shift key. Ed didn't make it clear how exactly it didn't work. Do you confirm that the only characters that can't be entered are uppercase letters? Also, Ed, how long have your 3 "known issues" been around? Right from the moment when the Dev Mode was unlocked?

The original variables and functions (preset of scripted) are all lowercase, but team names are capitalized, and many AI names contain uppercase letters as well. So lowercase-only input can be frustrating. The obvious workaround is to use scripts more, so that all command line statements can be lowercase.

Just confirmed it to make sure; only a-z cannot be modified by the Shift key, i.e., become uppercase. All other characters that require Shift can be typed. And thanks for the answer on what uses uppercase, the team names and AI names slipped my mind. I tested that as well, hoping that the Mac would ignore case, but alas; the console indeed does not recognize any team names without the uppercase letters. --Iritscen 04:02, 7 October 2008 (CEST)

Iritscen, you beat me to it. The SHIFT key does not work in Dev Mode to enter uppercase letters (I should have been more specific, sorry). How long have I've known these issues? The SHIFT key problem was discovered when you, (geyser) asked me to enter some code in the console, I forgot when that happened. The Window mode issue was known as soon as it was figured out how to run Omni group's version in a window. I'm sure this was mentioned at some point, either here or at OCF. The problems with the Numpad key was known back in Jan 2007 and you suggested using the key_config.txt file EdT 04:11, 7 October 2008 (CEST)

Large textures

The crash report is now history, but let's clarify the status of the patch at 0x001151C3. Is it irrelevant and can it be reverted?

0x001151C3 needs to be changed to 0x40 for 1024 textures, reverting to 0x04 or 0x10 results in crashes. Fortunately, I had already changed it to 0x40 prior to the latest patch.EdT 07:17, 22 October 2008 (CEST)

BSL functions

Cleaning up previous talk, see history if you need reference

1. Redeeming cm_barabus, because it looks like it works after all, and could be useful to both scripters and video makers (basically it interpolates the camera until it focuses on a certain character). So, Ed, please revert it.
2. Scrapping all 11 ai2_skill_* functions, because their table entries and strings are conveniently grouped. Putting 11 "essentials" there. If you want to tweak shooting skills, use another version ^_^
3. Keeping chr_holdkey as chr_location for now; may move it around later ^_^
4. Turning ai2_panic into equally useless chr_draw_dot; we may change it later ^_^
5. Turning ai2_chump into modder-oriented chr_who; we may change it later ^_^
6. Turning ai2_printbnvindex into ui_fill_element; we may change it later ^_^
7. For the big continuous patch you probably don't want to go nuts doing it byte by byte like I did, so grab a patched engine HERE and copy the relevant sections over to your backup. I used the big table below to proofread the patch, and we may still need it to check function pointers etc if something doesn't work.

BSL variables

Unsolved as of 06:39, 22 October 2008 (CEST). Needs a trimmed list of necessary PC vars matched with disposable Mac vars.

Since sc_bind_f2 and sc_bind_f3 won't work, the OTA needs to be rewritten whatever we do. Probably waiting for special anims should be replaced with waiting for hotkeyed variables like fast_mode (Ctrl+Shift/Alt+F), draw_every_frame (Ctrl+Shift/Alt+G), or gs_show_performance (Ctrl+Shift/Alt+Y). If this is done in the randomizer loop, there will actually be fewer contexts pushed than in the current version. There will also be no counterintuitive keypress sequences (F9,F2,F10), no spurious FILM files and no risk of buffer overflow. --geyser 06:39, 22 October 2008 (CEST)

Wishlist

Trying to list necessary variables off the top of my head (omitting sc_bind_f2 and sc_bind_f3, which won't work): --geyser 06:39, 22 October 2008 (CEST)

1. co_display (to run stuff in dev mode without cluttering up the screen with debug messages all the time)
2. fast_mode (Ctrl+Shift/Alt+F)
3. draw_every_frame (Ctrl+Shift/Alt+G)
4. show_performance (Ctrl+Shift/Alt+Y)
5. li_center_cursor (to reclaim -noswitch; not sure it can be done)
6. chr_pin_character

Camera management

1. cm_distance
2. cm_height
3. cm_canter_weapon
4. cm_canter_unarmed
5. wp_scale_adjustment

Gameplay tweaking

1. chr_aim_width
2. chr_auto_aim_arc
3. chr_auto_aim_dist
4. chr_block_angle
5. chr_disable_melee
6. chr_weapon_auto_aim

Advanced stuff

1. chr_all_active
2. chr_disable_visactive
3. chr_draw_all_characters (pbly redundant of chr_all_active for the needs of OTA etc)
4. chr_lod (do we really need this?)
5. door_ignore_locks
6. gs_input_accel
7. gs_show_corpses
8. single_step (probably not needed; the hotkeys are enough)

Goofy

1. chr_big_head_amount
2. chr_mini_me
3. chr_mini_me_amount
4. wp_kickable
5. fx_laser_width
6. m3_fill_solid
7. m3_shade_vertex
8. gs_show_environment

That's 33, which is a lot. 25 if we kick out the goofy. 24 if li_center_cursor doesn't work.

Brainstorming

Below are two little tables and two big ones. The first table is variables that don't seem to work but probably do, with the special case of ai2_boss_battle beilng used in [compound]. Then there's a small table of "huh" variables that are almost certainly disposable. Then there are tables (mutually exclusive, but overlapping with the small ones): debug/display things (32 items) and not-likely-to-be-tweaked things (17 items). Those would disempower modders and hackers but wouldn't change much or anything for level logic. 49 variables is a lot, but we have to choose wisely, and may end up having to maintain two versions of the Mac engine, one with debug stuff, the other with stuff that is meant to be used in scripts. --geyser 05:14, 10 October 2008 (CEST)

I'll start testing the variables and those I find that do not have a visible effect, I'll add to the possibly broken and disposable section. EdT 07:08, 10 October 2008 (CEST)

Is it possible to add gs_show_ui? That would be useful when taking screenshots or videos without the HUD. I can maintain 2 versions of the Mac Engine, I think a very small number would need the debug features, but having more PC compatible commands will be more appealing since Mac users will be able to play more scripts. Plus it will make it easier for the script writers since there one script fits all! EdT 21:53, 10 October 2008 (CEST)

Ed, you can use ui_show_element(left,0) and ui_show_element(right,0) instead of gs_show_ui=0; and don't forget ui_suppress_prompt=0 and such. The compatibility of scripts, of course, is the main goal. I just wanted to make sure you backed up the versions prior to those rewiring of mine because we are screwing with the engine in hackish ways and may want to take a few steps back. --geyser 02:01, 11 October 2008 (CEST)

Thank you, I did not know about that command, that saves one variable :-) I seem to recall another PC command door_ignore_locks used in some script, this might be useful... EdT 05:40, 11 October 2008 (CEST)

According to Neo sc_bind_f2, sc_bind_f3 cannot be added because the are strings and neither can gs_fov_set be added. However, he was able to add co_display and door_ignore_locks EdT 00:38, 16 October 2008 (CEST)

He was able to add them? So he gave you the fish after all? ^_^ If you want to allow me to give you more fish this week-end, please document the new fish in more detail, so that I know what disposable variables I can no longer use. As for gs_fov_set, it's a pity, gonna ask Neo what's the matter with it. --geyser 01:18, 16 October 2008 (CEST)

For Reference, Neo's changes

co_display = _COgDisplayConsole

var pointer: at 0x1B9E90 - REPLACE 0x00195D2C with 0x0027A1B9

wp_kickable = _WPgPlayerKicksWeapons

name string: at 0x171098 -REPLACE "ai2_showsounds" with "wp_kickable", 0

var pointer: at 0x1B9DB0 - REPLACE 0x0018EDC2 with 0x00192B05

EdT 04:29, 16 October 2008 (CEST)

Just curious, why wp_kickable? I have tried, and I cannot figure out what is stopping Konoko from kicking weapons...Gumby 05:36, 16 October 2008 (CEST)

I'll probably change wp_kickable to something else. wp_kickable allows the AI's to kick or move the weapon that's on the ground, but Konoko or the player cannot. EdT

That's 32!!! ^_^ however, the last 5 are not registered in the common table, so we actually have access to 25 vars: enough to accomodate everything except the goofy.

BSL variables available on the Mac that we're not too likely to modify in level logic

bool ai2_barabbas_run=1	"lets Barabbas run while carrying his gun" (disposable if we never need 0)

bool ph_debug_keyforces=0	"toggle keyboard applied forces" (no visible effect)

That's 16, but the last 6 can't be used (marketing_line_off is used and the other 5 are "registered elsewhere"). So, 10.

Summary

All in all, we apparently have a maximum of 35 disposable variables, and a total of 31 on the wishlist. My suggestion:

If li_center_cursor works, leave these 4: ai2_spacing_cookies, ai2_spacing_enable, ai2_spacing_weights, ai2_barabbas_run.

If li_center_cursor doesn't work, leave these 5: ai2_melee_weightcorrection, ai2_spacing_cookies, ai2_spacing_enable, ai2_spacing_weights, ai2_barabbas_run.

Maybe don't keep anything and add 4 or 5 extras instead, like draw_every_frame_multiple, gs_screen_shot_reduce...

Convert stuff "en masse" (there will be large contiguous blocks in the table, and in the name/description pool as well, although less so).

The 3 blocks are as follows:

1. ai2_showpaths
2. ai2_showgrids
3. ai2_showdynamicgrids
4. ai2_showpathfindingerrors
5. ai2_showconnections
6. ai2_showactivationpaths
7. ai2_showastar
8. ai2_showcombatranges
9. ai2_showvision
10. ai2_showprediction
11. ai2_showtargeting
12. ai2_showlasers
13. ai2_showlos
14. ai2_showprojectiles
15. ai2_showfiringspreads
16. ai2_showlocalmelee
17. ai2_showfights
18. ai2_shownames
19. ai2_showhealth
20. ai2_showjoblocations
21. ai2_showlinetochar
22. ai2_showsounds
23. ai2_printspawn
24. ai2_blind
25. ai2_deaf
26. KEEP DEFINITELY
27. ai2_chump_stop
28. ai2_stopignoring_count
29. ai2_stopignoring_time
30. ai2_melee_weightcorrection (keep if no extras and li_center_cursor doesn't work)
31. ai2_spacing_enable (keep if no extras)
32. ai2_spacing_cookies (keep if no extras)
33. ai2_spacing_weights (keep if no extras)
34. ai2_barabbas_run (keep if no extras)
35. KEEP DEFINITELY
36. ai2_showintersections
37. ai2_debug_localmovement
38. ai2_debug_localpathfinding
39. ai2_debug_showsettingIDs

(this does not necessarily correspond to contiguous strings)

And our wishlist is like this:

1. co_display
2. fast_mode
3. draw_every_frame
4. show_performance
5. li_center_cursor
6. chr_pin_character
7. cm_distance
8. cm_height
9. cm_canter_weapon
10. cm_canter_unarmed
11. wp_scale_adjustment
12. chr_aim_width
13. chr_auto_aim_arc
14. chr_auto_aim_dist
15. chr_block_angle
16. chr_disable_melee
17. chr_weapon_auto_aim
18. chr_all_active
19. chr_disable_visactive
20. chr_draw_all_characters
21. chr_lod
22. door_ignore_locks
23. gs_input_accel
24. gs_show_corpses
25. single_step
26. chr_big_head_amount
27. chr_mini_me
28. chr_mini_me_amount
29. wp_kickable
30. fx_laser_width
31. m3_fill_solid
32. m3_shade_vertex
33. gs_show_environment

33, to which we can add 4 or 5 extras like draw_every_frame_multiple, gs_screen_shot_reduce...

My impression is that there's plenty of space to accomodate all that. So let's do it.
