Maybe I dreamed this, but I thought there a C-Script function that, given x and y coordinates on the screen, would return the name of the texture, if any, at that spot. So if you clicked on any block or prefab, you could get the name of the texture at that spot on the screen. Do you have to use c_trace and tex_name? I thought there was an easier way. Does anyone have example code for getting the texture name at certain x,y coordinates on the screen this way?

Hello,

if I'm not mistaken you have to use c_trace.
With something like the following you should be able to get the texture name at specific screen coordinates:

Code:

---

// screen_pos.x/.y should contain the screen coordinates
// length_of_trace.. well, it is what is says

var vec_from[3];
var vec_to[3];
 
vec_set(vec_from, vector(screen_pos.x, screen_pos.y, 0));
vec_set(vec_to, vec_from);
 
vec_for_screen(vec_from, camera); 
vec_to.Z = length_of_trace;
vec_for_screen(vec_to, camera);   
 
c_trace(vec_from, vec_to, IGNORE_MODELS|IGNORE_SPRITES|SCAN_TEXTURE);

---

Thanks so much for this. And if I don't know who long the trace needs to be (I just want to trace until I hit the first block, I could do this in a loop, eh? Start with a short trace and then keep extending it until I hit a block?

Anyway, I think I've got easier solution now to achieve what I was after, but I'm glad to know how to do this for the future.

Thanks again.
