From 8d382e49fb3411cad1a3ef5ee1e546030c3a9d93 Mon Sep 17 00:00:00 2001 From: James R Date: Tue, 17 Nov 2020 04:14:45 -0800 Subject: [PATCH] Big Large Lua Hooklib Refactor * Hooks are no longer a mess of lua boiler plate. Helper functions reduce hooks to, at the most basic level, only two calls. * Lua tables (the array part) are used to index hooks. Such tables contain only hooks of the same type. * Hook types are defined in one place so you no longer need to sync up the enum and name array. --- src/b_bot.c | 6 +- src/d_clisrv.c | 12 +- src/d_netcmd.c | 10 +- src/doomtype.h | 2 + src/g_demo.c | 2 +- src/g_game.c | 10 +- src/hu_stuff.c | 2 +- src/lua_hook.h | 191 ++-- src/lua_hooklib.c | 2630 +++++++++++++++------------------------------ src/lua_script.c | 4 +- src/lua_script.h | 2 +- src/m_menu.c | 4 +- src/p_enemy.c | 2 +- src/p_inter.c | 16 +- src/p_map.c | 8 +- src/p_mobj.c | 22 +- src/p_setup.c | 4 +- src/p_spec.c | 4 +- src/p_tick.c | 12 +- src/p_user.c | 40 +- src/s_sound.c | 12 +- src/s_sound.h | 10 + src/sdl/i_video.c | 2 +- src/y_inter.c | 2 +- 24 files changed, 1055 insertions(+), 1954 deletions(-) diff --git a/src/b_bot.c b/src/b_bot.c index d3635f32c..93a853dee 100644 --- a/src/b_bot.c +++ b/src/b_bot.c @@ -75,7 +75,7 @@ static void B_BuildTailsTiccmd(mobj_t *sonic, mobj_t *tails, ticcmd_t *cmd) return; // Lua can handle it! - if (LUAh_BotAI(sonic, tails, cmd)) + if (LUA_HookBotAI(sonic, tails, cmd)) return; if (tails->player->powers[pw_carry] == CR_MACESPIN || tails->player->powers[pw_carry] == CR_GENERIC) @@ -363,7 +363,7 @@ void B_BuildTiccmd(player_t *player, ticcmd_t *cmd) CV_SetValue(&cv_analog[1], false); // Let Lua scripts build ticcmds - if (LUAh_BotTiccmd(player, cmd)) + if (LUA_HookTiccmd(player, cmd, Hook(BotTiccmd))) return; // We don't have any main character AI, sorry.
