Show focus information (healthbar and name)

[szapp]

Show the healthbar and focus name of NPCs that is being aimed at (and only as long as they are being aimed at!). The focus collection (from Focus.d) does not free the focused NPCs. Thus, another possibility would be to shoot a trace ray and if the intersection polygon is an NPC show their healthbar (how?).

Idea

Set focus collection to a small angle. During aiming check if focus vob is in a narrow angle (oCNpc::GetAngle) in front of the player model (center is [0.5, 0.5]). If the current focus vob is not in that angle, clear focus vob. Remaining question: Will the focus collections (Focus.d) then continuously set the new (correct) focus vob?

This approach is not satisfying. It is, however, available in the branch focusbyangles.

Improve trace ray

• Exclude origin vob (hero)
• Set flags to (zTRACERAY_VOB_IGNORE_NO_CD_DYN | zTRACERAY_VOB_BBOX) (1 + 4 = 5), or (zTRACERAY_VOB_IGNORE_NO_CD_DYN | zTRACERAY_VOB_BBOX | zTRACERAY_STAT_POLY | zTRACERAY_POLY_NORMAL) (1 + 4 + 32 + 128 = 165)
• Check if trace ray changes input arguments (vectors)
• Experiment with zTBBox3D::GetSphere3D and zTBSphere3D::IsIntersecting

[szapp]

This here does not give any results (always returns zero) and does really make sense to me anyways:

const int zTBBox3D__GetSphere3D = 5528768; //0x545CC0
CALL_RetValIsStruct(24); // sizeof_zTBBox3D
CALL__thiscall(_@(her)+124, zTBBox3D__GetSphere3D); // zTBBox3D
var int sphere3d1; sphere3d1 = CALL_RetValAsInt();
CALL_RetValIsStruct(24); // sizeof_zTBBox3D
CALL__thiscall(MEM_World.foundVob+124, zTBBox3D__GetSphere3D);
var int sphere3d2; sphere3d2 = CALL_RetValAsInt();

const int zTBSphere3D__IsIntersecting = 5521632; //0x5440E0
CALL_PtrParam(sphere3d2);
CALL__thiscall(sphere3d1, zTBSphere3D__IsIntersecting);
var int answ; answ = CALL_RetValAsInt();
MEM_Free(sphere3d1);
MEM_Free(sphere3d2);

MEM_Info(ConcatStrings("Sphere test returns: ", IntToString(answ)));
