Just playing around with the assets here, and although they look great, they're kinda awkward to use within rpg maker, I know it's for all general purpose but since you are listening I thought I'd let you know anyway. Because of the way RPG maker works if a player wants to interact with something it happens on the square tile itself, but a lot of the assets take up 2 squares because of their size and the dead space on either side. This in turn means that if we were to "use" the bathtub, the player would stand on either the left or the right side of the tub but not in the middle. Same for a lot of the sinks. A lot of the assets are also "floating" since they're not touching the bottom of their cell, meaning if the player was to interact with it, he would either step on it or be blocked from it some pixels away. This sort of break the nice illusion created by these beautiful assets. Maybe down scaling everything a bit would do the trick, so the bathtub for example takes up a 1x3 grid instead of a 2x4. Funnily enough with the bathtub, this is already what happens if you insert the filling of the tub animation. This actually means that it makes it very hard to layer those two on top of each other, empty tub with the filled tub animation. Hope you understand where I'm getting at. I know it'll be a lot of work and I surely don't expect you to go through all of the assets any time soon to fix these small corrections. But it would make your asset pack a lot more user friendly, and I think there's a whole community of RPG makers who are craving good graphics like these that doesn't feel as bland as the RTP.
Mmm I see I see...
Ok, the problem is that many objects are not designed to have a square collission box, since the Rpg Maker is the only software that forces that . I can try to shift every object that doesn't touch the bottom of the tile so the RPG Maker character can interact with them without being distant. For the bathtub example, I have no idea why the animation of te bathrtub works the way you mentioned since it's the sprites are placed in the same way on the grid, that's weird. Down scaling breaks proportions and require a lot of time, so I won't do that.
Also, I'm gonna add a suggested plugin on the asset page, since there are some out there that rewrite the collission system of the RPG Maker, and even the step length of the character, meaning that every now mentioned issue would be fixed.
I found this plugin for the MZ that allows you to set a custom character step length! The MZ is fairly new, but I'm sure in the next few months some useful collision plugin will come out!
Love the tenacity, just wanted to share that the MZ plugin doesn't really work that well and I just had a chat with the creator who said he doesn't recommend using it. So I think maybe remove that recommendation so it doesn't fall back on you for recommending it ;) Keep up the good work, always happy to see what improvements you come up with.
