This bug was originally discovered whilst testing for MCPE-178055 and MCPE-177283
In recent previews, holding down the use/place button, will only result with a single boat being spawned. Multiple boats can still be spawned in by double-clicking or spam-clicking (as long as there isn't another entity in the way).
Steps to Reproduce:
Pick a boat (in creative)
Hold down the use/place button, whilst aiming at a block.
Start strafing, whilst keeping the place/use button held.
Observed Results:
Only one boat will be summoned.
Expected Results:
Multiple boats should be summoned, like in 1.20.51.
The underlying issue seems more apparent from MCPE-178063: when holding down the button to place/spawn an entity, the target block/position does not update with player movement.
This may even be considered a duplicate, and perhaps MCPE-178063 should be generalized, if it affects other item-based entity spawning, for example with spawn eggs, minecarts, and armor stands.Edit: does not affect spawn eggs, minecarts, or armor stands.
