Changing sprite frame

[saboteur]

Managed to stuff my back over the weekend so am sat at home twiddling my thumbs so i thought i'd get back to JagStudio.

 

I have a sprite (24 x 24 px ) which has 3 frames of animation, so the image is  24 x 72 ( verticaly stacked )

 

I've been able to display my sprite and move it around no problem - but as soon as i try to change the frame I get a jumbled mess.

 

Is this code correct ?

pframe = 1
pgfx_loc=sprite[player].gfxbase
pgfx_size=sprite[player].framesz

sprite[player].gfxbase = pgfx_loc+(pgfx_size*pframe)

The rapinit looks correct and there is nothing in there that i can see where you specify the number of frames.

 

Thanks for any advice.

My initial thought is, you are changing gfxbase. Therefore on the next change, you have altered the starting address.

 

Perhaps store the initial gfxbase on game start, then always adjust the "live" gfxbase from that.

yeah, sorry

pgfx_loc=sprite[player].gfxbase
pgfx_size=sprite[player].framesz

is called at the start and outside the loop

 

I think my code is correct, i may have my rapinit wrong somewhere, think i'll see if OMF's tool gives me the same settings for this image

Well that's a bust - OMF's tool only allows images that are 16 or 32 pixels wide, perhaps that's my problem here.

Nah, never mind...

 

Helps if you asset file is pointing at the right image in the first place DOH!
