Just as a quick update, again I think this is a nice little template and 100% am happy with what it gives.
For those interested, if you run into an issue when having the character enter the bathroom Room, it is due to the rain particle trying to be referenced when that is not active in this room.
A simple check for: if (room != Room_Bathroom1) around the oParticle_rain.Step event code section. Something like this:
if (room != Room_Bathroom1) {
part_emitter_region(global.particle_system, emitter_rain, xStart - 600, xStart + camera_width + 600, yStart - 50, yStart - 50, ps_shape_rectangle, ps_distr_linear);
part_emitter_stream(global.particle_system, emitter_rain, global.rain, 5);
}
All in all I still stick with my positive review.
