First step in game making, need advises from pros

[SP6MEN]

Hello,

Made a few posts a while ago asking basic questions and such, i'm now to the step where i'm making a basic game engine for my game. In this post, i won't speak about my game ideas, not that i don't want to share my ideas ... but i'm far from really creating my game, before, i need a solid game engine ... this post is more about :"Is the direction i'm taking good"?, "What i have done wrong and how i could optimise it?", ...

So, i spent time searching and browsing on the web, found lots of interesting stuffs, and decided to take example from a french guy called " Spring up Spring up", it look like he has a good vision of how a sprite rpg'ish game should be made.

He seemed to have a good collision system (Best and easiest to understand i seen from now). Only problem was i want a click mouse rpg, like diablo, 8 directions RPG are good ... for consoles, PC are about mouses. I adepted one of Spring up example, to be used with mouse, but i ran into multiple problems :
1. I need to use an object controled by the mouse, i can't figure how to use 'real' mouse cursor, when playing windowed, not being able to move the mouse out of the game window is a **** in the **.
2. Adapting from 8 direction to mouse problem caused problems with link walking animations, sometimes there's no animations, sometimes walk animation speed up.

It seems main problem is with how i coded mouse control, i had to add a counter, tweak things, well i don't now, but it doesn't seems the right way to do it ... even if it works as it is.

I also started to code a way to have have roof going off when you enter a house, it's very basic, need a lots of tweak, but seems to work correctly (For me).

So ... how it look for you, any ideas, improvements, suggestions, ...?
Thanks in advance.

There are expressions you can use to get the mouse position without using the mouse movement. They are XMouse an YMouse.

As for the roof thing, could you simply make the roof invisible/visible?

And for mouse movement, there is the good-old Pathfinding Object, and good-new Advamced Pathfinding Object. These should help greatly for that.
