Ok, so i'm trying to recreate the Chrono Trigger game so i can learn how to do tiling, combat system, etc., the only problem is, the tiling is messing me up.

This is the room i'm trying to recreate (for testing proposes).
Edit: The pics now atttached.

Now my question is, how do i make it so when you (the character) hits the bed, you don't stop on a certain tile, but acually stop next to the bed. Would i have to make that bed a sprite? or would i have to use layers (don't know how to use layers by the way). I know this is a bit confusing, but if someone could help that would be great.

I'm not very experienced with creating 2d games, but I would assume you'd do a form of collision detection either way. For something like the bed, you could do a sprite, or if you wanted to save some space and effort, make a collision box instead. Same goes for the perimeter of the room. I would personally go with a method of setting it up so that your game would check the character's x and y coordinates and if they were either more or less than the x and y boundaries you set, you would make it stop you. Not sure if I helped at all, but hey, I tried
<EDIT>
I painted up your picture to give you a better idea of what I mean.

Green is the actual space of the map that you could walk in if there were no sprites to collide with.

Red is the sprites that you could collide with.

Blue is your x and y axis.

Enjoy my artistic skills, they don't shine very often haha

I'm not exactly sure what you're asking, but I'm pretty sure you have the right idea. Just remember not all objects are actually sprites. Some are merely part of the background image with a collision box around it.

First let me say there are so many ways to do sprite collisions you could get really deep into the water.

Since you are using tiles though, one of the easiest ways is to make a collision mask. It actually might be the oldest way too. Make the bottom layer of your tile engine the collision layer. If that tile is red or whatever color you want you have collided with something. Just check the pixel color at the cardinal compass directions from your sprite, if its red you can not move that direction. One of the benifits of a collision mask is that you can make it whatever shape you want and it will still work.

Could someone explain or show how i could use a "collision mask" for my game because i'm not even sure i know how to do layers, let alone a collision mask.
