Hi Ok, I am making progress slowly. I have started with the the pl data from Boojumsnark's library and then have modified it. I believe it's better to use the template from the library and then use my own codes (names of pathtracks, payloads, etc) that way I actually LEARN instead of just being a copy-cat and the experience has ben interesting so far. So at first, I got cart working and no visibal trainwatcher and the game ended at first point. Then I got the cart and watcher working together by reducing the amount of cap points to 8 (max) I had 13 over 4 stages - now I just have 8. Then after I got it working - the game crashed - actually locked up my pc forcing a restart when the cart got to the end ot the first stage. Have double checked the coding and found an error and the first stage works correctly - no more crashes Now this is the way my map works. Round 1 End cap at track 10 - do the coding for end of round - car then rolls by itsself down the track to point 11 (about five feet further down the track from where the round ended). At point 11 I have onpass = stop. Round 2 OnRoundStart = resume cart. cart is coded to be pushed - it no longer does auto movement thing < or at least I think it is. What haapens at round 2 is the clock goes 5,4, victory. Does anyone know what's going on? Where do I start to look for the error? Have I ended round one correctly? Thanks.
