Hello, if it is in the wrong sub-forum I apologize. I’m still not sure what goes where around here... I need some advice/help to get me started on a project: Creating a grid based road tool. The player should be able to left click on the ground and drag his mouse, when the player releases the mouse a road is created. If the player changes row and column with the mouse the road should make a turn. Only orthogonal roads supported so if you “turn” it should drawn an L-shape, for example. I was thinking of making a grid made up out of simple 3D rectangles an positioning the camera above them as to create the grid visual, then simply change the texture colour of the selected ones. Now the first issue is that I’ve not really done anything with the mouse as input before, mostly keyboard/controller. Secondly not sure how to do the actual selection: I’d imagine the ones you mouse through would have to be added to an array/list which upon releasing the mouse button would colour them in..?
