<aside> ⚡ script "core_NewUniqueTID" (void)
</aside>
This script is a wrapper for [UniqueTID](<https://zdoom.org/wiki/UniqueTID>) that can be used alongside its sister scripts in DECORATE to emulate the behavior of A_SpawnItemEX flags which Zandronum does not yet support, such as SXF_ISTRACER or SXF_SETTRACER.
The TID created by this script will also be stored for later retrieval by [core_CurrentUniqueTID](<https://mm8bdm.notion.site/core_CurrentUniqueTID-3b0cafaaeed04af4b6cbdc9ed43e2449>). However, it must be cleared on the same tic that it is created by using [core_ClearUniqueTID](<https://mm8bdm.notion.site/core_ClearUniqueTID-5e67156647094a15bb4376d8f2426936>).
Returns a unique TID.
The example below emulates SXF_ISTRACER while creating a projectile which is essentially two pellets which orbit around an invisible center piece.
