[Axe] Gravity Walls
« on: August 08, 2012, 08:25:28 pm »
Hi guys !

Here is my current Axe project : Gravity Walls !

In this gravity-based game, you are a man trapped in a room with only one chance to escape : a small door.

But there is a problem ... this door is sticked far on the wall ! Yeah, this room is kind of special ... In the background, there are arrows, and these arrows decide where go the gravity ; if you go on them, the gravity switch in the direction of the arrow. And since you follow the gravity, you can access to the door by using these arrows !

There will be many levels, but for now I only did the map engine and the physics, and separately.

Mapper :


Physics :

Are you a big fan of Leafy ? It reminds me a lot of Graviter (by Leafy) in which the player would control the character from Tag (by Leafy too) O.O
Otherwise, it seems like a great project :D

Idea: make two same sprites, and in a loop:
Code: [Select]
0->I
[xxx]->Pic0
[xxx]
.the two sprites are the same!!
While(xxx)
I=I+1%8
Pt-On(0,0,Pic0+I)
EndI is used like a offset ;)

Well, in fact I use an Axiom I codded for this game :P it's just bits and bytes manipulations in the arrows' image. I did it in ASM to have fast commands.
