Hello.
A simple contribution :

It works well for 'unlimited' (radar) objects using pan_create.
Have fun !

EDIT :
Adjust the radar's range by changing the make_scan.z value :
function init_radar {
panel_radar.visible = on;
make_scan.z = 2000; // radar's range
panel_radar.pos_y = screen_size.y-198;
shadow_threshold = 30;
}

If you wanted constant radar elements, you should use this code :

loved that in the movies! one of the best radars i know

thanks and cheers

Thank you, gOmO_3!
good contrib, but have to look at code deeply (demo not functioning properly for me /A6_comm_3.14/, do you use 6.40 update ?)

A great contribution definately credits worthy thanks!
By the way, does anyone have some tips concerning a 'level radar' ? My plan is to make a radar on which also lines are visible from buildings (most probably they are models too, but I only want an outline), I remember I must have got some code which will draw a the boundary box lines, so it must be possible somehow.. I want to keep it simple though, anyone some suggestions for this?

Cheers

@Gomo_3: Awesome job!
@Phemox: I don't know how the lines would be drawn like you want 'em, but have you looked at Locoweed's Minimap/radar scripts?
Maybe the minimap would be a good start for this?

This radar code is great, I've changed somethings so it works as a regular radar, usable in my top-down game (i mean, camera indepent, player dependent, just changed 3 words in the code ) and it works great, I'm using A6.4 com btw...

@Daedelus: Thanks for the link to Locoweed's site, I think that his radar code will be pretty useful indeed for what I had in mind, thanks. I've also seen some other interesting topics there, like a simple AI example, I'm going to check those out asap...

Cheers

Thanks to everyone.
@Lion_Ts : I'm using the 6.40 Update but it should work with 6.314, too. The only new functions I have used are pan_create and panel.scale_x which have been available since 6.3. What is the error message ?

Mmm, after some fiddling with this code, and changing it for my needs, there's something strange happening. At the edges of my radar, when the enemies are just getting in range (or just out of range) the dots get like twice the size, instead of being really small, or invisible. Anyone have an idea why this happens? Like I said in one of my previous posts, only things I've changed is camera.x into player.x, wherever the camera was involved. It must be the math when certain values get past some range, it's kinda confusing, because it's working fine, except this size blow-up when they are at the range area of the radar...

The zeros are my 'problem' , I want them either invisible, or super small sized, not twice the normal size ...

EDIT: Nevermind, I've got it solved ... I've just added ;
Code:

---

if(pan_temp.pos_x - rader.pos_x < 25){break;}
			   if(pan_temp.pos_y - rader.pos_y < 25){break;}
			   if(pan_temp.pos_x - rader.pos_x > 100){break;}
			   if(pan_temp.pos_y - rader.pos_y > 100){break;}

gOmO_3,
hero in downloaded demo flies up, marks on radar not at the 'real' places (all at radar bottom). but nevermind. i think your code is good (for 6.4), i'll try to look closer at it (for my old 6.314 ), when have free time. thank you for contribution

How big is your radar panel? You might have to adjust certain values. The 96 in 'radar.pos_x+96' and radar.pos_y+96' has to be your panels size/2, to get the dots in the middle of your radar panel. Do you use the radar for a first person shooter? Because the way it's originally coded is for a radar dependent on the camera, not the player.

Cheers
