An edit of my other script: No Crumpkins.

This script assigns a custom model to Crit Pumpkins (aka Crumpkins) immediately as they spawn.

To make it work on your Halloween map, put this script into scripts/vscripts/ folder and create a logic_script entity with the following parameters:

Entity Script...........................custom_crumpkins.nut
Script think function..........Think

Click to expand...

In addition, you need to edit the line #4

CUSTOM_CRUMPKIN_MODEL <- "models/yourmodelhere.mdl";

Click to expand...

and replace models/yourmodelhere.mdl with the actual model you want to use.

And don't forget to pack the script (and the model) into your map!
