Break and Place, Not Break and Replace

umbral_knight

Trying to get a spell that whether I am sneaking or not will switch between breaking and placing a single block, but the placing needs to be placing it on the side I am aiming at not replacing the block and adding another as well. Any help would be appreciated.

Also here is the copy code:

I think you're trying to overcomplicate something rather simple. It's worth noting that in vanilla Psi, you're not "intended" to be able to change the effect, so depending on the situation combo spells like that aren't always possible. The usual method involves using the error catcher and forcing a different default using math based on your sneak status. It's not needed here though.

Caster raycast (using caster location and look vector) is the location of the first block in your line of sight. The sum of caster raycast and caster axial raycast is the block space in front of the block you're looking at. These are the basics. This space will always be air because your raycast didn't encounter a block there. Because of that, doing a break block trick there does nothing. There's the trick to doing what you want. Simply multiplying the raycast axis by 0 or 1 using sneak before adding the raycasts toggles between the block you're looking at vs the block before that. Trick: die prevents the place block trick on anything between -1 and 1. If you had wanted to place as the default and shift to break, then just using sneak for both would do the job, but you want the inverse. For trick:die, just doing cosine of sneak is the usual method since cos(0) is 1 and cos(1) is almost 1, but in this case you need to do math with the number, so I rounded down.
My preference would have been "break or replace" since block swapping or getting under sand/gravel when mining are more important to me than placing 1 block at a distance, but here you go. I posted this using an older version of the mod, but all the pieces should be the same. If it doesn't paste right, just recreate the image.
