Editing the sprite sheet?
No, not rude at all. I have reviewed other's code and, normally, reviewing and tinkering with other's code really helps me learn things. It seems to me that a file is loaded into one of the GRP's (GRP4 seems to be prevalent), and SPDEF is called. I'm just having difficulty finding the connection between it all.
Ah, alright thank you! So I create the sprite sheet in the Smiletool, save the file (as a GRP4 im guessing), then I can load the GRP4 file and it will become the 'default' sprite sheet, or the one that is being used? Or must I designate it with SPDEF in some way? EDIT: I'm using the smiletool to edit the sprite sheet, though i notice that some sprites are larger than others. If I were to erase the sprite sheet and start fresh, and since this sprite sheet thing is one giant image, how would the system know where a sprite I create begins and ends?
You need to use 2 things:
1. A image editor(Smiletools is good but I recommend TH. GRP Editor).
2. SPDEF to define sprites that have different proportions or locations than the default sprites.
With SPDEF you can define:
-The upper left corner where the sprite start (parameters U,V)
-The size (Parameters W,H )
-The center of the sprite (Parameters Origin X, Origin Y)
-Transformation (Parameter Attribute)
The last one is a binary representation of a transformation. You need to put it with the syntax &B[Binary] (Example: &B0001 ) or a number.
The position of each "1" will do something to the sprite.
For example the code "&B1001" display the sprite and do horizontal inversion to it. That means that if the sprite is facing right on the sheet, then it will face left for the definition number used in SPDEF. You can see more about this function using the "?" icon.
