AHH Ur breakin my brain THIS IS AWESOME how’d you do the click raytracing for interaction? ---

render() uses traceRay() to trace a ray into a block, and so I made the clicking do the same thing. traceRay() returns a number[] like this [face, distance, face x, face y, voxel index, voxel x, voxel y, voxel z] and when placing a block, it adds/subtracts 1 to voxelX/voxelY/voxel and sets the block. Did that help? ---

because the ray tracer has a max amount of steps, so some of the house is never rendered ---

things like: ```javascript //% block="..." ``` or ```javascript //% shadow=... ``` Often is very finicky when I use them. My first extension made (doesn’t work yet) was [Mini menu Trees!](https://forum.makecode.com/t/mini-menu-trees/41386/1) The issue was more the coding part, but I disliked using the //%… because of have to repeatedly change to blocks over and over again and the blocks would often glitch out [Previous page](https://forum.makecode.com/t/3d-voxel-rendering-engine/42425.md?page=1) [Next page](https://forum.makecode.com/t/3d-voxel-rendering-engine/42425.md?page=3)
