Since the introduction of the 1.24 server branch the following script functions no longer take effect on prims with a fair amount of mass, it breaks functionality and is just illogical. llSetBuoyancy llMoveToTarget llSetForce llSetHoverHeight The larger the prim the less effect the script function has. This also causes the very odd effect of things seeming to not function at all. A linked platform that is physical often will not hover even with typical move to target function. In 1.23 any size object could use move to target and achieve a hover or movelock effect. To reproduce you simply need create any solid prim that is 10x10x10 make it physical and use one of the affected script functions. They fail to take any effect. The most noticeable is buoyancy. A buoyancy of 10 should send any prim high into the air flying upwards, but on a physical 10x10x10 it falls to the ground like a heavy rock. default { state_entry() { llSetBuoynacy(10.); } }
