DZB2 mod for Battlefield 2

As shown in the images below, you need to additionally bind a convenient shortcut key for the **FLY BY** of ground vehicles and fighter jets. Of course, you can use the default F12 key. Personally, I recommend the G key.

This key will be used to switch the third-person view of the turret for ground vehicles with turrets (e.g., tanks) and the view for guided ground-attack munitions of fighter jets.

In any vehicle, press the Q key to bring up the options menu. You will see obvious green text options for selecting the style of the third-person crosshair for the vehicle. The "None" option disables the third-person crosshair display, while other options correspond to different crosshairs and HUDs.

• Ground vehicles with turrets (tanks, armored vehicles, etc.): Press the key you bound above to switch to the third-person view of the turret. Press the C key to switch to the traditional BF2 third-person view. In the third-person view, only the tank's main gun is set to fire directly at the center of the crosshair; other weapons will have slight deviations due to the height difference in the view, and you can correct the ballistics using tracer rounds. This function is implemented by switching to the secondary weapon (the weapon used for zooming). Therefore, when you switch to the turret's third-person view, the current primary weapon will switch to the next weapon (e.g., the tank's main gun will switch to the machine gun). You may need to reselect the weapon using the number keys or the F key. Selecting weapons with the number keys or F key will not affect the view switch. Only the bound button can switch both the view and the weapon.

• Fighter jets and helicopters: Press the default C key to switch to the third-person view. (This is a function from the original BF2, but the original view parameters were unreasonable, making it less useful.)

• Guided ground-attack munitions for fighter jets: Press the key you bound above to switch to the guided ground-attack view and weapon. Press it once or twice again to switch back to the cockpit view. Only some fighter jets have this function. Explore it yourself.
• For all guided ground-attack munitions in the fighter jet's view, fire using the left mouse button (primary fire)! Therefore, when you switch to the fighter jet's guided ground-attack view, do not use the right mouse button to fire missiles.
  
  
• Fighter jets without missile models: Allow the use of helmet-mounted targeting to guide air-to-air combat missiles. You need to select a third-person HUD to display the lock status first. Hold down the left Ctrl key and freely look around to use the helmet-mounted targeting to lock onto enemies with missiles.

• Guided Bombs

The crosshair style is as shown in the image below. Some fighter jets' HUDs do not have the small red cross in the center, but the function is the same.

In this view, hold down the left Ctrl key to release control of the fighter jet and look around freely. Press the left mouse button to mark the target and release the bomb. A red circle HUD marker as shown in the image above will appear, indicating the approximate impact point of the bomb within the circle. Before the bomb hits the ground, you can continue clicking the left mouse button to change the impact point. Remember to hold down the left Ctrl key to observe unless you want to directly control the aircraft's attitude to change the field of view. After marking the target, you can switch back to the cockpit view; there is no need to continuously guide the bomb, as it will automatically fly to the marked target.

Due to inertia in the game, the aircraft's attitude and bomb release position will affect the bomb's flight. Therefore, try to select targets in front of the aircraft when releasing bombs. Of course, these are essentially guided bombs, and as long as the flight attitude is not particularly odd, the bombs will hit the marked position. The camera's field of view direction will not automatically reset, so after releasing the bomb, you can align the camera's view direction with the nose of the aircraft for convenience in the next operation.

• Laser-Guided Missiles

The crosshair is as shown in the image below. These missiles require continuous guidance until they hit the target. Similarly, hold down the left Ctrl key to release control of the aircraft, then press the left mouse button to fire while keeping the left Ctrl key held down, and guide the missile until it hits the target. Remember to align the camera's view direction with the nose of the aircraft after the operation for convenience in the next operation.

• TV-Guided Missiles

Operated the same way as the classic TV missiles for helicopter co-pilots in BF2. Similarly, hold down the left Ctrl key when launching and guiding to release control of the aircraft, so that the aircraft's attitude will not be affected when you select the target. During the flight of the TV missile, you can judge the current aircraft attitude based on the green indicator lines, speed value, and altitude value displayed on the HUD.

Sniper Rifles

Most sniper rifles allow you to press the Q key in aiming mode to switch the magnification of the scope. Some semi-automatic sniper rifles have an added full-auto firing mode.

When in any vehicle, press the Q key. When the mouse pointer is on the circular "Spot Enemy" button in the center of the menu, press the right mouse button to bring up the map tone modification menu. You can switch to your preferred map color style as needed. This function can quickly change the map environment to night. If there are no vehicles in the map you are playing, use the assault soldier's radio beacon, press the E key to enter the radio beacon, and then perform the above operation.

Unfortunately, the direction of the shadows of static buildings on the map cannot be modified (they can only be re-rendered in the editor). However, different map environments and atmospheres can still bring more fun.

This system allows you to customize weapon combinations in real-time in the game. Weapon packs for different factions and classes are independent of each other and do not interfere with one another.

The underlying framework of this system was built by AGM114 Hellfire (Bilibili ID: 众筹收购蠢驴), and supplemented and improved by myself.

Due to the large number of option branches, the game may stutter for approximately half a second when pressing the weapon selection button. This does not affect game operation.

Select any soldier class first, and weapon icons will appear below—click the icons to choose your weapons.

If the map disappears, click the KIT button to restore normal display.

This mod uses direct object-level linking of vehicle codes to automatically replace vehicles spawned on maps. This eliminates the need to modify map files, and ensures strong compatibility with the original game and extended maps of AIX2. Therefore, the vehicle codes spawned on the map do not represent the actual vehicles spawned. For specific links, refer to the code in `XObjects_Server.zip`. The actual vehicle parameters are in `Vehicles_Server.zip`. If you need to modify them, make sure to find the correct vehicle entity. Additionally, if you modify the code for shared linking parts, you need to modify the linked vehicles together (e.g., adding/removing mounted weapons or modifying vehicle health requires changing the linking part, while modifying data for existing weapons does not require changing the linking code).

For example, the code `aix_mig19` actually spawns the `air_j10c` vehicle.

In some maps, when you turn on the thermal imaging/IRNV filter for the first time, there may be a strong flood of light. You can simply turn off the filter and then turn it on again to resolve this. If you end a game without turning off the thermal imaging/IRNV filter, the in-game colors will become incorrect at the start of the next game. In such a case, you just need to turn the thermal imaging/IRNV filter on and off once more to restore the colors to normal.

If you keep switching between different maps to play, a memory error will occur during the loading process when you switch to a new map at some point. This is because BF2 does not release the previous memory, which is determined by the game mechanism and cannot be fixed. Therefore, after playing several rounds, close the game and take a break.

Some weapons integrate an experimental real-time ammunition switching function. Tests have shown that weapons with real-time ammunition switching will cause the game to crash if used by AI BOTs. This is because BOTs read ammunition data in real-time and calculate ballistics when using weapons, and real-time ammunition switching interrupts this process, leading to a crash. However, it is safe to have these weapons in the inventory and only use them as a player. The following are the weapon codes; do not assign them to AI:

BF4_PLD

EMZPJ_Phantom_Bow

m32_mgl

javelin

bf4_xm25_player

If you need to add new maps, Add the following code to the Init.con of the map:

run ../../common/Scripts/AGMCustomization/function/loader.con team1_kits_split team2_kits_split

For example, a map of CH vs US

run ../../common/Scripts/AGMCustomization/function/loader.con ch_kits_split us_kits_split

Note: The three original factions' variables in this mod correspond to the original names, while the UN faction uses the EU's container variable name.

So, for maps with team1 UN VS team2 MEC, it should be:

run ../../Scripts/AGMCustomization/function/loader.con eu_kits_split mec_kits_split

Otherwise, the newly added maps cannot use the custom kit system. Adapting new maps is simple, requiring only one line of code.

I've added spawn points to some transport helicopters. In certain cases, if a helicopter pilot abandons a helicopter with a spawn point, and the helicopter crashes without exploding, landing in areas without AI paths, then if a bot respawns on that helicopter, it will cause the game to crash. I don't plan to fix this known issue for now because the probability of it occurring is very low. By contrast, having more mobile spawn points is more beneficial to the gaming experience. I think it's worth it. If you're really unlucky and frequently experience game crashes due to this issue, you can manually remove the spawn points on those transport helicopters.

Vehicles

`bf3_f35` and `bf3_f35vtol` have no sound when the engine afterburner is activated.

`j35` and `j35b` sometimes have incorrect perspective relationships for engine exhaust flames in third-person view.

Maps

The `AIX_Trident32` map has unknown random crash issues.

For TNG2 series maps, due to BF2 engine limitations and loading setting issues, the faction voices in some maps are incorrect.
