I was having trouble with the Spot light, but have now corrected the issue and this may be the same issue plaguing the radar gun mod. However using the radar now crashes my game, so Im trying to figure out the confliction that may be occurring.
The fix I found for spotlight; is that in the Script for GTAPolicingTools, the model names for spot light and the radar gun are incorrect. They currently show as gpt_radar and gpt_spot_06. In my effort to fix the radar gun I tried installing a new model via openiv which is where I noticed that the model names are tns_radar and not gpt. A quick edit via notepad and it fixed the issue, with the exception of crashing my game when the radar spawns. Despite this everything else works fine, so I hope this fixes the issue for some of you.
^^^ I hadn't updated my weapons.xml which brought on the crash. All is fixed now and its as simple as changing the text in the script and ensuring the code for the radar weapons.xml is correctly added to the common files xml. Only other issue that crops up with this mod is the spike strip failing to load after the first use. Tend to not let you do another as you have to dismiss it and even when you have dismissed it, it still wont load.
