I want to make my own character sprites but when i try to import it only take .chr files. what program do i need?
You are probably trying to import a whole character, not a sprite.
Sprites are imported in a sprite manager
https://adventuregamestudio.github.io/ags-manual/EditorSprite.html
Then sprites are inserted into a View:
https://adventuregamestudio.github.io/ags-manual/EditorView.html
Then this View may be assigned to a Character:

This is explained in the Tutorial too:
https://adventuregamestudio.github.io/ags-manual/acintro6.html
I recommend following a tutorial to learn how to start making games in AGS.
The tutorials and other information can be found in the manual, which is available in online form (it's the links I posted here), and in offline form as a ags-help.chm file with the editor. Offline manual can be run by pressing F1 in the Editor (or Help -> Contents in the menu).
There are also few tutorials on Youtube that may be useful:
The old tutorials by Densming (they were made for old version of AGS, but are still useful for the most part):

Newer tutorials by Eon Star:

Also, please, when making topics on this forum, give them proper descriptive titles.
Thank you my first game.
