Updates and Improvements

The Red Front is quickly verging upon the first Beta version. For the game, this means that the bulk of the games base features have been implemented.
The base features consist of the games systems (AI, Weapons, Upgrades, Weather, Cash, Mutations etc) have been implemented and are working as intended. The art style has been chosen, sounds are being implemented, bugs are being fixed and optimisations are being put in place.

Shields, Weather and HUD

The weather has once again taken a turn for the worse on The Red Front. There is now far more unpredictability in the weather cycles, it may storm one day, then rain or even snow the next. The storms have been growing in intensity with heavy rain and lots of lightning. Could this be foreboding at something evil to occur?

The soviet engineers have been working hard on the commanders tank HUD, displaying the most accurate information possible in a presentable way.
We will be continuing to implement more HUD features to give the commander the edge on the battlefield.

New Features Added

  • Dynamic Weather System

There are four new weather systems in The Red Front, the weather will be randomly chosen when you start a new level. The most common weather type is a normal sunny day. There is also rain, snow and a storm.
The storm may be hinting at something evil stirring on The Red Front, so stay alert to find why it is occuring.

  • Shield Particle Effects

When the tank commander has a shield up, any damage taken from an enemy will create a distortion effect on the commanders shield. This creates another visual queue for the commander to gauge their health.

  • New UI elements

The UI has begun to receive updates, the newer UI is far more sleek and informative. There will be additional features to the in game HUD added over the future.

  • Camera Screen Clamps and Screen Aspect Ratio support

The Red Front will now support the most common screen resolutions, the camera has been clamped to remain within the game world and will now overshoot the boundaries of the map. This helps prevent immersion-breaking game play and help the commander focus more upon the battlefield

Multiple bug fixes have also been made in the game, these vary from Soldier AI (stopping suicidal rocket infantry units) to fixing minor issues such as sprite lighting effects.

Unity Development Tutorial – Tank Turret Rotation

I’ve had some requests to create some tutorials showing how The Red Fronts back-end works. In a way of giving back to the game development community, I’ve decided to create some basic tutorial series that will be regularly updated.

Through these series you will get a look “under the hood” of the game and see how some of the code works. Those interested may choose to follow along with the development.


Unity – How to make a 2D Tank Game – Player Tank Part 1

This tutorial is based off the player-controlled tank for The Red Front which is currently in development.

Arcade-Action games are a very popular Genre. By following this tutorial you’ll learn how to create a playable tank, make its turret rotate and follow the mouse. In a later tutorial, you will learn how to make the tank move and make it shoot.

You will need to create some basic art, one for the “body” of the tank and one for the “turret” of the tank. These two parts will move independently to each other so will be drawn in two segments.

This tutorial has been written for beginners and assumes basic knowledge of Unity and C# programming.

Skill Level: Beginner

Prepare the game objects and link reference sprites.

The tank we are building will comprise of two separate game objects. One object for the “body” of the tank and one game object for the tank turret. The turret will move independently to the tank body and will be set up to track the player mouse.

The basic setup required for this is as follows:

  • Create two independent game objects in the unity hierarchy (Named TankBody and TankTurret).
  • Add sprite-renderer components to each of the newly created game objects, link your tank body art and tank turret art to each applicable game object
  • In the hierarchy view, drag and drop the TankTurret object onto the TankBody object. This will set the TankTurret object to be a child object of the TankBody object.

Following this, you will have the following hierarchy structure and objects created.

Note: If you have any issues with the turret appearing behind the tank body, select the TankTurret object and set the “order in layer” to 1.

Create a new C# script and attach it to the turret Game Object

The following stage will add a new C# script to the turret object which will cause the turret to track the player cursor.

  • Select the TankTurret object and Select Add Component
  • Click New Script, name it TurretTrack and make sure C# is selected for the language
  • Once the script has been added to the object, right click the script from the inspector when you have the TankTurret object selected and click “Edit Script” and paste the following code:

public int rotationOffset = 0; // This will offset the rotation of the object as it tracks the mouse. This is required to correctly set rotation values
void FixedUpdate() {
Vector3 difference = Camera.main.ScreenToWorldPoint (Input.mousePosition) - transform.position; // This will calculate the distance between the mouse in the game and the position of the tank turret
difference.Normalize (); // This returns simplified values which makes it easier to work with
float angle = Mathf.Atan2(difference.y, difference.x) * Mathf.Rad2Deg; // This calculates the angle between the mouse and the turret by using the values derives from the difference calculation.
transform.rotation = Quaternion.RotateTowards (transform.rotation, Quaternion.Euler (0f, 0f, angle + rotationOffset), 200 * Time.deltaTime); // This will rotate the turret towards the calculated angle over time. Tweaking the multiplication value will state how quickly or slowly it will rotate.

  • Build the script and you can then press the play button. The turret will now “almost” track the mouse

  • To fix the tracking issue, select the turret object and expand the rotation script. In the Rotation Offset box, write “270” so the script will offset the rotation of the turret by 270 degrees.
  • Press play again, you will now see the tank turret tracks the mouse properly.


You have now created your tank, created a moving turret and have it correctly following the mouse.

There may be some additional questions, so I have created a few example questions below:

  • Why has the script been added under “fixed update”?
    1. The Fixed Update receives a dedicated cpu timeslot, the update section is susceptible to frame-rate issues. It’s a good idea to place critical updates for your game in fixed update rather than update. As the player tank turret is core to gameplay, this script has been included under a fixed update.
  • I want the turret to follow something other than the mouse, is this hard to do?
    1. It’s fairly easy to do, you just need to reference another objects transform point and replace the screentoworldpoint method with the referenced objects transform (i.e. targetobject.transform.position)
  • I have other issues with the script and hoping you can help?
    1. Contact us on social media or leave a comment here, we will do our best to reply as soon as we can.

Bonus Segment, Sprite Rotation Point

If you would like your turret to rotate around a different central point, select the art piece that you have and click “sprite editor”. The central circle is the sprites rotation point, drag this to your desired location and hit “apply”. Everything else will magically just work!

About This Tutorial Series:

This tutorial series is being written by the developer of “The Red Front”, these tutorials are aimed at new unity users who are interested in getting involved in Game Development.
