hi,

Ive add the UCO packed in LFSLapper, which is working well.
https://www.lfs.net/forum/thre ... per-adding-ISP-UCO-packet

i have a question about it.

Is it possible to indicate the InsimCircle Index(Object index = 253) and Insim Checkpoint 1/2/3/F(Object index = 252)?
I have red the LytFormat file but i dont know how to code it.

Could someone give me a helping hand?

For the circle, the circle index is supplied in the Heading field.
Checkpoints don't have an index, but you can check their X/Y/Z coordinates.

Here i think it is better if the Checkpoints have also an ID to Check if a Car Drive over it. This would be easier.
