How do I change the size of animals ,monsters, or items?

I think you have to change some numbers in the config file of the thing you are trying to edit but i don't know which ones exactly to change.

 

I'll take the shark as an example :

First, modify its sprite. You can resize it and tweak it as you want, just keep the frame layout.

Then :
Here are some parts from the shark.cfg file :

Code:

@f32 verticesXY                      = 16.0; 12.0;  
                                     48.0;    12.0;
                                     52.0;    16.0;
                                     48.0;    20.0;
                                     16.0; 20.0;
                                     12.0;    16.0; 

Basically these are the coordinates of every vertex of the shark collision shape : Looks like x;y; x;y; x;y; etc.
For example 0;0; 10;0; 10;10; 0;10; will make a 1 pixel large square.
Multiply them by the resize ratio of each axis. (So if you made the shark as twice as long, multiply per 2 the x coords. If you doubled its size multiply per two all coords, etc)

Then you have to modify the sprite size :

Code:

$sprite_texture                      = Shark.png
s32_sprite_frame_width               = 64
s32_sprite_frame_height              = 32

So you have to modify the size of every frame.
Here again multiply by the resize ratio. Warning : It must be an integer, so no stuff after the .

Haven't tried, but it should work if it's properly written

 

Now to add in the chicken glide ability to make the almighty sky shark.
