Terraria AUTO-FISH tutorial

The code and ideas used in the tutorial are from 吾爱论坛, I am responsible for providing a clear and explicit process

This method has the following two disadvantages: 1, fishing, Terraria should be at the front desk, not in the background (Invoke the mouse click operation of Windows to realize the retraction and release of the fishing rod) 2, games can't completely shut down (though the window has been closed, but the process still exist, need to manually shut down in the task manager, the reason is a thread in the process of fishing, No good fix has been found for this bug.)

This works with Terraria 1.4.4.9

Tool using dnSpy

Please download the 32 bit version

Automatic fishing implementation

• Open the main Terraria program with dnSpy and decomcompile it
• On the left side of the program find Terraria - Terraria.exe - Terraria - Projectile
• Right click on Projectile and select Create Field, as shown in the red box

• In the window that is displayed, change the name to fishFlag and select static. Change the default type int to bool in the type column as follows: Click Clear, click Type, search for bool in the new pop-up window, and add the bool type as shown in the figure (note that bool type is provided by {}System), click OK to complete the creation

• As in the previous step, add a field named createdThread
• Right click on Projectile, select Create method, name it mouse_event, and select static; Add the input parameter type in the signature column by clicking the type button, searching for System.int in the new pop-up window (note that int type is provided by {}System), click OK, and then click Add. Repeat this process five times to add five int parameters

• On the left side of the program go to Terraria - Terraria.exe - Terraria - Projectile - mouse_event (font color is orange), right click < GT R ="37"/>, select mouse_event, In the right code area, add using System.Runtime.InteropServices; to the top declaration and replace the red box with the following code

[DllImport("user32")]
private static extern void mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo);

• When finished, click the compile button in the lower right corner of the window to complete the creation of the mouse_event method
• Right click on Projectile, select Create method, name it DoFish, and click OK

• On the left side of the program go to Terraria - Terraria.exe - Terraria - Projectile - DoFish (font color is orange), right click DoFish, select Edit Method (C#), in the right side of the code area, Add using System.Threading; to the top declaration and replace the red box with the following code

public void DoFish()
{
	int millisecondsTimeout = 1200;
	for (;;)
	{
		if (Projectile.fishFlag)
		{
			Projectile.mouse_event(2, 0, 0, 0, 0);
			Thread.Sleep(100);
			Projectile.mouse_event(4, 0, 0, 0, 0);
			Thread.Sleep(millisecondsTimeout);
			Projectile.mouse_event(2, 0, 0, 0, 0);
			Thread.Sleep(100);
			Projectile.mouse_event(4, 0, 0, 0, 0);
			Thread.Sleep(100);
			Projectile.fishFlag = false;
		}
	}
}

• When finished, click the compile button in the lower right corner of the window to complete the creation of the DoFish method
• On the left side of the program go to Terraria - Terraria.exe - Terraria - Projectile - FishingCheck (font color is orange), right click FishingCheck, select Edit Method (C#), In the code area on the right, add using System.Threading; to the top declaration section, and at end, under the if function (where the arrow points) add the following code:

if (this.bobber && this.Name == "浮标")
{
	if (!Projectile.createdThread)
	{
		Thread thread = new Thread(new ThreadStart(this.DoFish));
		Projectile.createdThread = true;
		thread.Start();
	}
	Projectile.fishFlag = true;
}

• When finished, click the compile button in the lower right corner of the window to complete the modification of the FishingCheck method
• Find Terraria on the left side of the program, left click, then click File in the top left corner of the program, Save the module, select Path, and OK

• In this way, you can successfully decompile and save to the EXE file, run the saved EXE, fishing in the game to see the effect

Offline Play implementation (with no Steam)

• By commenting the code that initializes Steam information, you can do so without logging in
• On the left side of the program go to Terraria - Terraria.exe - Terraria.Social - SocialAPI - LoadSteam (font color is orange), right click LoadSteam, select Edit Method (C#), In the code area on the right, delete the red box in the figure

• The Steam online save is located at C:\Program Files (x86)\Steam\userdata\[your steam id]\105600\remote, which changes depending on where your Steam is installed and what your Steamid is
• The offline save is stored in the %userprofile%\Documents\My Games\Terraria path
• some other details

Terraria - Terraria.exe - Terraria - Item - SetDefaults //Initialize the item properties, you can change the damage and efficiency of individual weapons here
Terraria - Terraria.exe - Terraria.GameContent.ItemDropRules - ItemDropDatabase //Dropped items and probability, the probability is the reciprocal of the value, for example, a value of 20 represents a probability of 1/20

Terraria - Terraria.exe - Terraria - Item - buyPrice //buy price
Terraria - Terraria.exe - Terraria - Item - sellPrice //Sell Price
Terraria - Terraria.exe - Terraria - Player - Hurt //Inflicted damage. After testing, it may be related to the invincibility frame, but not much. The value does not affect the damage. If you return a number directly, you will be invincible. Negative effects such as burns cannot be immune.
Terraria - Terraria.exe - Terraria - Player - GetWeaponDamage // all weapon damage calculations are here

If an error occurs when compiling the type or namespace name "ReLogic", go to Terraria - Terraria.exe - Resources to see if there is a similar dll, and export the dll to the same directory. .
