Sprite Editor

[Ekmek]

resetting stuff to 0 seemed to work. I tried a few turns and it worked and made another, boat, sprite. but then I loaded a new sprite, it ran etc and I did it just like the other ones, then at the end of the turn the game crashed. Then reloading the game I didnt add any of the other ones and now the settler sprite crashes again. not sure whats going on.

[Martin the Dane]

As far as I hav been able to figure it out the fields are as follows:

Sprite Num Frames = the number of actual images available for the selected animation.

Sprite First Frame = this is the number of the first image imported when using makespr.exe (the Apolyton sprite generator) What it does in the game, or the sprite-file I don't know. Just keep it at 0 or 1 to be safe

Anim Type = the way the animation is played in ctp. sequential plays through from the first frame to the last defined frame, looped starts over at the first frame when it's gone through all of the frames, back-n-forth reverses direction of playback when it reaches the last frame, and playes back to the first before reversing direction again.

Anim Num Frames = the number of frames in the animation, these frames are realy just a list of numbers, refering to Sprite Frames.

Anim Playback Time = the time to play the animation sequence, not used in Civ:CTP, not sure about CTP2

Anim Delay = Amount of time to display the last frame before repeating, don't know how it is messured.

If you have not done this yet, it is a good idea to read the first part of documentation that came with makespr.exe (I have attached it to this post)

I have not had the time to look into why SpriteEdit allows import of wrong-sized images. I won't be home much over the next week or so, so I can't promise anything.

[The Big Mc]

Martin spritedit does not save the image size. on build 12. this means that the sprite may be displayed distorted or as e said not appear.

[Martin the Dane]

I just checked, the size is saved to the sprite-file, but somehow I have managed to eliminate the check for image-size on import. (Probably happend when I rewrote the import routeens) I'll add a check in the next build, but when that will be I don't know.

E, if you have the time, I would apreciate it if you could try using the same size for all images, and see if this solves the problem. This will help eleminate other causes for the problem.

[The Big Mc]

I will say something I think e image is innocent of the bug I replaced the north walk with a image I knew could not case a problem (a giant blue box) this also caused the game to crash . but I can’t shake the thought I had a similar problem with the active$ion sprite maker.

[Ekmek]

Yeah,
I eventually went in and redid the sprites to keep them all the same size. I thought it worked, one game I did a few turns and everything was going great (for 3 sprites I made using sprite edit no less) then a crash happened and since then I'm back to square one, where a settler moving crashes it again. I'm loss at to what else to do now. I too shall take a break and maybe think of something I did wrong.

thanks guys.

Where can I find a good sprite packer/extractor that works with any sprites? All of them I have found only work for a certain game/program. I am trying to make graphics for my buddy's game, and I cant find anything that will work.

[The Big Mc]

That’s probably because there are different types of sprite file for example

In ctp the sprite files hold graphical data however in another activsion game called star trek armada sprites contain text which can be edited in note pad so to answer you question I don't think there is one or will be one.


however if you buddies game is ctp there is the sprite edit on martin the dane signature will work.

Martin, BigMC

I revisited my crashing setler sprite. here are somethings I notice.

At start up the fidget is great, then I move and it crashes BUT if I add an archer (another sprite I created) and move it, then I can move the settler BUT then it crashes I think its when the AI moves its settler.

If I make everything visible and do the same add an archer it seems to work fine for awhile

THE REAL WEIRD test was that I decided to swap my galley sprite I made in place of settler and it worked on start up. So I thought maybe it was an error with the settler sprite I copied over. So I copied settler graphics over the galley AND it still crashes!!!!!!!!!

I think the game recognizes something unique with a settler sprite which might be the problem or maybe it is my graphics.... any suggestions???????????

[Ekmek]

I THINK I Achieved SUCCESS

I finally went and redid my death.tgas which were at 104x77 instead of 96x72. Before my graphics were mixed and Martin when you wanted me to mae them one size I changed them all to 104x77 and it still crashed. I think your problem is in the handling of different sizes because all ofmy 96x72 sprites work perfect.

[Ekmek]

Martin,
Sprie editingis going well, but I noticed that if I add fraes to a sprite the animations won't show because it remembers the original sprite frame delay. Also changing the center points do nothing also.

[Martin the Dane]

Hi E,

I must admit I have not been working on SpriteEdit lately. I am aware of the problem with handling frame size, this is one of the reasons SpriteEdit canot create sprites from scratch. I'll have to look into the frames not beeing played.

[Ekmek]

Martin,
Thanks. I'd say if anything adding the playing of all frames would be ore important than the resizing (mainly since a lot of sprites can be used as templates and I can post any bigger ones if people need them).
