1. You add the item you want to respawn (ex. item_hlvr_grenade_frag), and a point_template entity.
2. Set the point_template to use the item entity as a template.
3. Add an "OnPlayerPickup" output to the item entity targeting the point_template entity with a "ForceSpawn" input.

Set the delay to whatever feels right to you.

How did you make the items respawn after being taken

Awesome Shooting Range. Nothing but what you need.

do you create other blue shift maps?

Made an updated feedback video here. Nice job fixing the issues, though I'd like to hear more varied voice lines and also have an easier way to handle weapon upgrades. https://youtu.be/8-pplHjKgkE

"All that time at the shooting range is gonna pay off today!"

Nice map

"i need to get patched up"

Waiting for this to become CS:VR

Great! I really enjoyed the map, otherwise.

Yeah I'll have to take a look at the zombie issue, see if I can't fix that.

Sometimes it's the little things that make a map worth playing and replaying. In this case, it's Barney's sweet, sultry voice. Nice job! The only issue I noted was when spawning too many zombies. More details in this video: https://youtu.be/tizTsPA9Nsc

nice!
