Tutorial

This page explains how to draw a frontline on the map similar to how it is done in the Operation Cobra campaign of the Spearhead 1944 CDLC.

Create Layer

Create a layer in Eden Editor called Frontline Control Points. This layer is referenced by the function to generate the frontline data points

SPE Frontline Ingame.png

Create Markers

Inside that layer, create as many markers as needed to shape the frontline (The wavy black line). These markers act as control points for bezier interpolation and their position will influence the curvature.

⚠
The more markers you place, the more accurate your frontline will be, but the calculation will be more expensive and generating the data will take longer.

SPE Frontline Ingame.png

Start Preview

Execute the following code in the Arma 3: Debug Console from within Eden Editor to create a real-time preview of the frontline Close the window that shows up for now. We will need it later.

[[], nil, "preview"] call SPE_MISSIONUTILITYFUNCTIONS_fnc_generateFrontline;

SPE Frontline Ingame.png

Shape Frontline

Now drag the previously placed markers to shape the frontline. You can also add new markers by copy and pasting an existing one.

Generate Data

Once you are happy with the shape of the frontline, execute the following code again in the Arma 3: Debug Console from within Eden Editor. Instead of "high", "very high" and "ultra" are available, although data generation will take significantly lower and the visual improvements might be neglegeable.

[[], nil, "high"] call SPE_MISSIONUTILITYFUNCTIONS_fnc_generateFrontline;

Create Data File

Once the data was generated a window will show. Copy the content of the window and paste it into a script file. Place this script file into your mission folder. In our case we call it frontline_data.sqf and place it into the root of our test scenario

Add Code

Add code that creates frontline for every client to the init.sqf. The script has local effect and thus needs to be run on every connecting client. Clients without interface are automatically excluded (headless clients, dedicated server)

init.sqf

[ call compile preprocessFileLineNumbers "frontline_data.sqf", ] call SPE_MISSIONUTILITYFUNCTIONS_fnc_generateFrontline;

Function Syntax

Previews a frontline in Eden Editor, or depending on parameter, generates data for it so it can be created during runtime. Path of border is defined in Eden Editor by placing markers of type "Select". Preview is updated if a marker is moved.

Syntax

[[], nil, "high"] call SPE_MISSIONUTILITYFUNCTIONS_fnc_generateFrontline;

Parameters

Index Data type Description Default value
0 Array Data for placing the fill markers inside frontline. If this data is provided the function assumes that the frontline should be created during mission runtime. Leave this empty for previewing in the Editor []
1 Boolean True to draw axis area, false to not false
2 String Quality setting of the exported data
  • "preview" - Used for preview, resolution is 500 m
  • "very low" - Resolution 32 m
  • "low" - Resolution 16 m
  • "normal" - Resolution 8 m
  • "high" - Resolution 4 m - WARNING: Generating data can take several minutes!
  • "very high" - Resolution 2 m - WARNING: Generating data can take several minutes!
  • "ultra" - Resolution 1 m - WARNING: Generating data can take several minutes!
 "preview"
3 String CfgMarker color of the inside fill "SPE_ColorAllies"
4 String CfgMarker color of the outside fill "SPE_ColorAxis"
5 Number Alpha of inside marker 0.6
6 Number Alpha of outside marker 0.6
7 Number Interpolation quality of the border. Lower value means it's smoother, but generates more data 0.002

Example Scenario

Limitatons

As of Spearhead 1944 v1 there are some limitations:

  • Only one frontline can be drawn
  • Frontline can only be drawn from top to bottom e.g. as shown in the images above
  • Outside area marker can be drawn on top of inside area markers. This will be fixed with Arma 3 logo black.png2.14
