Radar class

[s0beit]

Simple radar class, it uses D3D9 but it can operate without D3D9 (engine)

The D3DRender class simply handles some D3D9 rendering techniques, replace that with your engine drawing class/functions

The colors are static, meaning you have to change them in the class, but ill upload a pic soon

nice wurk

[SgtDrew]

Very nice

[CallMeEclipse]

Super-Terrific Neat-o job!

[Chod]

On a mission to release your entire project feature-by-feature? :P

[s0beit]

not really, i just had a tiny bit of trouble converting it from source engine and thought i would save somebody some time, lol.

honestly, other than detection i don't know whats stopping anybody from making a full, awesome hack.

everything is on these boards.

lack of skills perhaps?

Nawh, some people just keep some things to themselves.

Awesome. Thanks a lot for the source. I am adding this to my BoxESP.

What is exactly "YAW" in GetViewAngles()[ YAW ]?

[.Encore]

#define PITCH      0
#define YAW        1
#define ROLL       2

PITCH: up and down, YAW: left and right, ROLL: side to side

Thanks a lot
