Place model\image\sprite in constant position on screen

**Bugsy** · **Author**

I am trying to place an image on the screen that will remain at a constant position regardless of player view movement. I am a 100% noob with calculating angles and all that jazz so any help will be appreciated. The overall goal is to have a image rest behind a HUD message as a background. Possible?

I think the best way is to build the model so it's in a position on your view and attach it.

Using a sprite would be need some calculating angles. If I'm right you have to calculate the eye position ( pev_origin + pev_view_ofs ) then adjusting to put more in left, right etc..

This is the part that I am totally clueless on. Maybe stupok will chime in for me since this is his area of expertise

Both me and stupok, tried to put sprites as if they were in the hud but with no success, when the user moves. The sprite position is always delayed. I even tried to added the vector velocity but it just make it worst. Maybe it can be achieved but I doubt it.

This is the code I was using:

PHP Code:


			
ent = create_entity("env_sprite")
entity_set_model(ent,spriteModel)
set_pev(ent,pev_scale,0.02)
DispatchSpawn(ent);

PHP Code:


			
static Float:start[3], Float:view_ofs[3], Float:origin[3]

pev(id,pev_origin,origin);

new Float:angles[3]
pev(id,pev_v_angle,angles)

new Float:path[3]

angle_vector(angles,ANGLEVECTOR_FORWARD,path)
xs_vec_normalize(path,path)
xs_vec_mul_scalar(path,4.0,path);
xs_vec_add(path,origin,origin)

angle_vector(angles,ANGLEVECTOR_RIGHT,path)
xs_vec_normalize(path,path)
xs_vec_mul_scalar(path,-2.5,path);
xs_vec_add(path,origin,origin)

angle_vector(angles,ANGLEVECTOR_UP,path)
xs_vec_normalize(path,path)
xs_vec_mul_scalar(path,-2.0,path);
xs_vec_add(path,origin,origin)

new Float:vofs[3]
pev(id,pev_view_ofs,vofs)
xs_vec_add(origin,vofs,origin)

entity_set_origin(ent,origin);
set_pev(ent,pev_angles,angles)

About this code, you shall create the entity anywhere and then use a forward, i tried with PlayerPreThink, to do the calculations.

Bugsy, if you are still interested in this:

I have been playing with it more and with AddToFullpack and setting the entity movetype to MOVETYPE_NONE I managed to make it.

Problems: going through ladders or barely walking with cl_bob bigger than 0 makes it move (And I doubt that it can be fixed). Still, if you want to use it in clients without speed it works fine.

Edit: I mean stairs not ladders
