Auto-Aim Turret Tutorial

I've been seeing a lot of players here asking how to do auto-aim and not being able to figure it out, so I wanted to make a definitive tutorial since it is actually not that hard.

I may or may not also be using this for a current project.

This uses the turret FT made by SenSkysh, so all credits go to them. They also have a video tutorial in the comments of the linked post, but it can be a bit hard to follow.

NOTE: THIS TUTORIAL IS DESIGNED FOR COMPUTER USERS, BUT IT SHOULD BE POSSIBLE ON MOBILE AS LONG AS YOU CAN USE GOOGLE SHEETS.

Step 1
Go to this spreadsheet. Then, click File/Make a copy. Name your new file autoaim or whatever you fancy. A new window will open with your new spreadsheet. Once you have done this once, you can skip this step, as you now have the spreadsheet.

Step 2
In SimplePlanes, create your turret. You need a rotator for your heading (horizontal traverse) and elevation (vertical traverse). IMPORTANT: Change your rotators to 10 degrees rotation!

Here is what mine looks like. I have colored the rotators yellow.

Step 3

Now, we have to do some funky trees. I have named my turret Turret1, but you can name it whatever you want.

Funky Trees inputs: Please refer to this as you go. This is an image since the website still doesn't support less than or greater than in the code text. Plus, hopefully, you'll learn better by actually typing this out.

[VARIABLES]
Open your variables tab and add these variables.

[PART : ROTATOR : HEADING]
Put this into your heading rotator input.

[PART : ROTATOR : ELEVATION]
Put this into your elevation rotator input.

The purple text is required to ensure that the turret returns to zero when there is no target or the target is outside the turret's range. If you still want the turret aim at a target outside its range to the best of its ability, remove the blue text in Turret1Range.

Notice that we have a 0.1 multiplier because our rotator is 10 degree rotation, which will translate an input of 1 into a rotator output of 1 degree. This is required because the turret code will output the degrees of required rotation.

[VARIABLE : TURRET1RANGE]
In the variables tab, put this into the variable Turret1Range. The blue text will disable the turret when a target is outside its range. The angles should match your minimum/maximum heading/elevation and the distance is arbitrary and optional.

[PART : GUN]
Put this into your wing gun/gatling gun/cannon activationGroup. The green text is optional and will make your gun start shooting when it has been on target for a certain amount of time. A smaller smooth value will increase this time.

The red text is optional and will make your turret activate with an activation group (in this case, AG2).

Step 4

Now, lets refer back to the spreadsheet.

First, we must input the XYZ coordinates of our cockpit. We then input the XYZ coordinates of the turret. IMPORTANT: Use a comma for the decimal!

Then, check the boxes if you want the turret to lead the target (you probably do) and if your turret is a cannon. Then, input the velocity of your turret's projectiles.

Input the Left Angle, Right Angle, Up Angle, and Down Angle. These are the minimum/maximum heading/elevation in degrees. IMPORTANT: Left Angle and Down Angle should be negative. Then, input your start heading. 0 is forward-facing, 90 is right-facing, 180 is rear-facing, and so on. You can also input the roll position if necessary.

Using these values, the spreadsheet will spit out the code you need.

Step 5

Now, we input the actual turret code. In the spreadsheet, click the cell containing the elevation code and copy the text using RMB/Copy or Ctrl+C. Now, go to SimplePlanes, open the variables tab, and paste this code into the Turret1Elev variable with Ctrl+V. Repeat for heading and Turret1Hdg.

Now, if you have done everything correctly, you should have a turret!
