What is the sensor range from bottom left to top right I.E. on a tag sensor? Not essential information but would be handy to know. Sorry for not being clear yes the whole level. I.E If I place a tag sensor in the bottom left of an empty level what would be the exact distance to the top right.

What do you mean, of the entire level? If you set the max range to 5000 I'm pretty sure that covers the whole workable space, regardless of where your sensor is within it.

I am not sure, but if you hooked up a rope or piston from top to bottom it would give the distance...I thin it is around 4000 wide and less high..perhaps 1000? I know that around 3000 was the piston distance in the first one to link both side of the level with pistons.

Have just done a couple of tests with some interesting results. test 1 string :- 4364.8 test 2 tag sensor :- if you place the sensor in the corner and a tag in the opposite corner then increase to 5000 it doesn't activate. But if you have the tag and sensor together then move them into opposite corners it stay active at 5000. Then when you turn the range down it goes off at 4600 and won't come on again at 5000 unless you move it closer first. So I still don't have a definitive answer. However as I said this is use full but not important. Thank you everyone for your help and contributions.

This is not the answer to your question in the OP, but a discussion related to the weird sensor behavior (hysteresis) you describe in the above quote. https://lbpcentral.lbp-hub.com/index.php?t=23046-A-quick-guide-to-Hysteresis&highlight=sensor+hysteresis

Does this mean that the sensors can't reach the widest part of the game then?

Does this mean that the sensors can't reach the widest part of the game then? No, they can, but you will have to test for the analogue component of the signal. The analogue component measures (roughly, when the minimum distance is set to 0): 100%*4*(max_distance-distance)/(3*max_distance) which is then rounded up to zero if it's negative or down to 100% if it's above 100%. So you'll need to check the analogue component. I am not sure how it behaves when set to "signal strength" mode - it may alleviate the hysteresis problem. I would try this first because if a tag is just there, or is being activated with a 100% battery, the analogue signal is just 100%. The digital signal may be just 1 as well.

Worst case scenario, use 2 sensors set to 5000 on different sides of the level and connect them to an OR gate.
