2d compass 2D Compass calculations

[Flash-Ranger 195]

Hello all,

I'm trying to script a 2d compass (based on code I found on internet, not mine) but I'm really not good at maths. If you are please explain to me in simple words or detailed explanations so I can understand and reproduce.

 

My issues :
1. I can't make it align with north correctly
2. I can't figure out how to change it's width without destroying it's rotation

Size of my picture 4096*4096 pixels.

I don't get the math in it but I guess _dir could be just

_dir = getDir player;

 

EDIT: strikethrough

Up ? Any one to help ?

Why use math?

disableSerialization;
MyCompass = findDisplay 46 ctrlCreate ["RscPictureKeepAspect", -1]; 
MyCompass ctrlSetPosition [0.5,0.5,.1,.1]; 
MyCompass ctrlSetText "\A3\ui_f\data\map\markers\handdrawn\arrow_CA.paa"; 
MyCompass ctrlCommit 0;
addMissionEventHandler ["EachFrame",{
	MyCompass ctrlSetAngle [getDirVisual player, 0.5, 0.5]; 
}];

You can get around the serialization error message by using "with UInamespace do", depends on how you set it up.

Because my 2D compass is Horizontal linear. I want it to slide left or right depending on the orientation of the player

Use linear conversion then?

 

You're not really specific about what you want.

When the bearing is 0 the slider should be full left, at 360 full right?

 

Could be something like this:

_dir = getDirVisual player;
_newMin = minPositionX;//some x coordinate the image should have when the player bearing is 0
_newMax = maxPositionX;//some x coordinate the image should have when the player bearing is 360
_positionX = linearConversion [0,360,_dir,_newMin,_newMax,true];

Why not share how you solved your issue?

Deleting topics won't help others that might run into similar issues.
