is-this-c · 2025-09-23T13:42:02Z

Changes derived from Alpine Faction's source code
- Improves compatibility with Alpine Faction network protocol
- - Flags::allow_fb_mesh
- - Flags::allow_no_ss
- - Flags::no_player_collide
- - Flags::allow_no_mf
- - Flags::click_limit
- - af_damage_notify_packet
- In Alpine Faction levels
- - Handles AlpineLevelProps::legacy_cyclic_timers
- - Allows triggers to activate events in multiplayer
- - Fixes events that broke if their delay parameter was set
- - Supports loading Alpine Faction's $Lightmap Clamp Floor, and $Lightmap Clamp Ceiling, $Crater Texture PPM, and $Mesh Replacementfrom {map_name}_info.tbl
- - Supports dynamic lights
- - Makes particle emitters placed in levels respect their active distance parameter

I did not bother cleaning up af_options.cpp so it is just a copy paste.

This PR is getting out of hands. It's really hard to review 1000+ changes (125 commits) multiple times. It takes me a lot of time and I'm still not sure if I didn't skip something. Can you split it into smaller PRs instead of making one big PR with everything? You add new stuff with every revision and fix unrelated stuff like adding const everywhere. If you must add it, okay, but not make huge PRs like this which changes 10 things at the same time. And all those commits have bad titles like "Update". Should I squash them and be left with one big commit in the git history? Every unrelated feature should have it's own commit/PR. Big PR for adding all Alpine stuff is a bad idea.
Small PR would also make it easier for me to find time to review it...

game_patch/graphics/d3d11/gr_d3d11_mesh.cpp

+        const bool ir_scanner = (params.flags & MRF_SCANNER_1) != 0;
+        if (!ir_scanner) {
+            rf::Vector3 ambient_light{0.f, 0.f, 0.f};
+            light_get_ambient(&ambient_light.x, &ambient_light.y, &ambient_light.z);


why it was moved? I can see in RF code that those builtin lights are used for characters too

That is in render_v3d_vif which is for e.g. item pickups. Characters are lighted in render_character_vif.

game_patch/graphics/d3d11/gr_d3d11_mesh.cpp

+        const bool ir_scanner = (params.flags & MRF_SCANNER_1) != 0;
+        if (!ir_scanner) {
+            const bool allow_full_bright = !(get_remote_server_info()
+                && !get_remote_server_info().value().allow_full_bright_entities);


there should be no negation or it should be "deny", not "allow", because currently it makes no sense

const bool allow_full_bright = !(get_remote_server_info() && !get_remote_server_info().value().allow_full_bright_entities);

seems clearer in expressions e.g. if (config.full_bright && allow_full_bright) instead of if (config.full_bright && !no_full_bright)

const bool no_full_bright = get_remote_server_info() && !get_remote_server_info().value().allow_full_bright_entities;

game_patch/misc/af_options.cpp

+AlpineLevelInfoConfig g_af_level_info_config;
+
+// trim leading and trailing whitespace
+std::string trim(const std::string& str, bool remove_quotes = false)


why this file recreates entire parsing module for no reason introducing bugs like not handling escape character in strings? You just copied it from Alpine right? Looks like AI slop :(

I didn't have the energy to go through it since it was an isolated file.

rafalh · 2025-10-26T21:19:39Z

game_patch/misc/level.h

-struct DashLevelProps
-{
-    // backward compatible defaults
+struct AlpineLevelProps {


of course Goober had to copy my way of handling that, but of course he didn't try to handle my chunk, right? I wonder why he didn't make new cyclic timers depend on rfl version

Alpine Faction handles both chunks. legacy_cyclic_timers does depend upon RFL version. See event_type_forwards_messages_patch.

game_patch/misc/af_options.h

+};
+
+struct AlpineLevelInfoConfig {
+    std::unordered_map<std::string, std::unordered_map<AlpineLevelInfoId, LevelInfoValue>> level_options{};


what is this, some kind of cache that you never clean? another AI slop?

Goober agreed it should be for the loaded level only. I've changed it.

game_patch/object/object.cpp

-    [](rf::Object* objp, const char* name, rf::VMeshType type) {
-        rf::VMesh* mesh = obj_create_mesh_hook.call_target(objp, name, type);
+    [] (rf::Object* const objp, const char* name, const rf::VMeshType type) {
+        const std::input_iterator auto level = g_af_level_info_config


level? that's a stupid name. Better mesh_replacements or replacements, because i'ts clearly not a level...

Yeah I missed this somehow.

game_patch/object/particle.cpp

+    int,
+    rf::Particle**,
+    rf::ParticleEmitter*
+)> particle_create_level_emitter_hook{


this name is confusing, it's pretty much a patch for ParticleEmitter::spawn method, but the name suggests it's some kind of constructor for particle emitter itself.

It is called particle_create? What about particle_spawn_level_emitter_hook?

rafalh · 2025-10-26T22:01:33Z

game_patch/rf/particle_emitter.h

    float current_state_time;
    bool active;
-    int field_144;
+    int active_distance;;


Double colon. Also is there a way to set this field in editor?

rafalh · 2025-10-26T22:03:30Z

game_patch/object/obj_light.cpp

+            && !get_remote_server_info().value().allow_full_bright_entities);
+        if (g_game_config.full_bright_entities && allow_full_bright) {
+            // For Direct3d 11, we set in `gr_d3d11_mesh.cpp`.
+            rf::Vector3& ambient_light = addr_as_ref<rf::Vector3>(0x01C3D548);


it's ambient_color, not to be confused with 005A38D4. I didn't check in PS2 code, but that's how it's named in my PC data

From IDA:

ambient_color.x = g_ambient_light.x * 255.0; ambient_color.y = g_ambient_light.y * 255.0; ambient_color.z = g_ambient_light.z * 255.0;

Is it not the same?

rafalh · 2025-10-26T22:08:44Z

game_patch/object/event.cpp

+            // RF does not allow triggers to activate events in multiplayer.
+            // In AF levels, we allow it, unless it is an event that would be 
+            // problematic in multiplayer. 
+            const rf::EventType event_type = static_cast<rf::EventType>(event->event_type);


(opinion) great idea, enable all events without any synchronization of the game state between server and client, especially late client. It probably introduces some quirks and even bugs, but who cares

Good point. But seems too late...
