Has anyone a nice idea on how to visualize a scan cone?
Would be handy.

i think you could create a cone in med, and unitary cone, like 1x1x1
then you on runtime, mesh deform the cone, using the mesh functions, to place the vertices on the range you used for the cone and etc etc. Have you though that?

how about constructing it with draw_line / draw_line3d ?

Thank you for your fast replies.
I´ve thought on both methods but they are quite complicated.
Maybe there´s be an easier better way.
If not, I´ve to dig alot into vector math.

you dont need to dig to deep.

i mean the cone is facing a direction right , to you define a line that points the directions.

then from that point you trace a perpendicular line, with the lateral range of the cone, (laterals and z laterals) then the point of the cone origin, and those lateral limits, will do another line, which is the cone "areaa" but in planes only.

hey Fogman, long time since our last talk.

you could use the delphi routines I wrote in Delphi SDK that do just that:

procedure Debug_C_Scan(Entity : PEntity; Angle : PAngle; Scan : PVector);
procedure Debug_DrawLine_ToFront(Entity : PEntity; Dist : Var_);
procedure Debug_DrawBoundBox(Entity : PEntity);
procedure Debug_DrawTriggerRange(Entity : PEntity);

for the Debug_C_Scan it's called right after a c_scan with the same paramerters to graphically display the range of the c_scan operation

used like this:

if ShowDebug = 1 then
Debug_C_Scan(ev.me,@ev.me.pan,_vec(15,15,125));

I will update the SDK Homepage to have the actual DLL's there so non-delphi users can use them too. I will update the page this weekend.

Mr. Michael Messerschmidt, I love you.
Thank you very much!

Thumbs up! Works like a charm.

One thing though: In "Delphi_A7_DLL.h"

void Debug_C_Scan(ENTITY Entity, ANGLE* Angle, VECTOR* Scan);

has to be

void Debug_C_Scan(ENTITY* Entity, ANGLE* Angle, VECTOR* Scan);

fogman, very glad to help out!

good catch with that incorrect prototype. I will change that for the next release.
