Ok I have everything set up. An explosion effect etc. But I want the object to detonate only on contact with a moving biped. How would one go on about this? Since I dont want it to detonate after seconds after dropping the object. Because of the way I set it up as. (More of an oddball styled mine.)

Hmm.I've not tried something like this yet but you can place a trigger volume over the mine and make a script which detects if the player has entered the trigger volume, then make it explode. You might also want to use the ai_actors command for the list of ai you want that can trigger the mine. That way, anything entering the area of the mine (trigger volume) will make it detonate. (Also possible with objects.)

I would do that, but my trip mine works over the fact where you can place it anywhere... If only I could attach a trigger volume on the actual object D:

So what would happen to the triger if the mine eds upsidedown? Never detects a biped! ... It has to be something about the distence of a player to the mine I think but I honestly don't know anything about this stuff.

Effects can spawn bipeds or vehicles.
You can also script the mine to create a biped or vehicle.
Make a 'portable trigger volume' by using the 'object_can_see_objects' command, so if a plyer is near the mine (seen by the object) it wil asplode.

One method was to create a constant effect on the trip mine which fired many invisible projectiles in a 360 direction, which disappeared after a short range (the higher the projectile life, the larger the trip mine explosion range). When this projectile encountered the cyborg shader, it would detonate, otherwise disappearing.

Whitch leaves you whit the fact the mine will work for a centrain time and not just for 1 player to end whit a b00m... Sorry mithrill but that won't work. What we need to figure is how to make the mine when tronw on the ground or sticked to something become an tricker like a race_track point. The race track point would detect the player excactly the way we need here. So how to make the race_track point spawn when u lay the mine? Also a tip: Give the mine a time delay for the one that placed the mine so he/she can get away from the mine.

Uuuh... no.
You can't just script in or place gametype markers. There are no 'moddable' commands for that.

I don't quite understand what you're saying. How does it only work for a certain amount of time? The effect is fired constantly, forever.

E: Cause I had nothing better to do: http://www.xfire.com/video/27d7e3/

Proof that it does work. Ignore model\textures. Apologies for the lag, and if the radius is off.

This guy? speaks the truth. The truth would be more apparent if I didn't blink though >>

A mine using this method is available for download on Halomaps, just a fyi.

srs where. I feel un-needed ):

Don't worry; yours is still prettier, albeit causing unnecessary blinking >>

Pretty sure that method involves creating an effect in the footsteps tag when it encounters a certain material. I tried that method before using engineer materials, and it never seemed to work for me. :S

I meant that the mine won't disapear when it kills someone. Also the effect of the explosion is missing. Unless you can make it detect when it kills someone.

Can be done.

Are you seriously blind? Re-watch the video.

Magic shall be worked.

:D I should have watched the video :D

You should have. Mythie worked long and hard to prove you wrong; his effort shouldn't be in vain ;P

lol he didnt watch the video

20 mins? Actually, it doesn't disappear after killing someone atm, but Jesse is fixing that hopefully <3

And I spent twice that time getting you a new model, animating it, and re-tagging your weapon tag >>

that one that one from that campaign looked good
