By calling sprite s,x,y,s every loop, I don't think it will ever play your animated frames.

You need to establish a variable that controls the status of your character. For example, when the right key is pushed, you update the status variable and set the lower and upper frames for the play sprite command. During the main loop, if the status is jumping or moving right, you play the sprite, otherwise you just call sprite s,x,y,s.

Any chance you could upload the sprite images (or email them to me if you don't want to post here). I would be easier to check it if I had them.

I'm not really a programmer.....I only play one on TGC.

That is a .gif image and not two .png images as listed in your code. If you need to convert it, you could use GIMP, which is free. Here is the link:
http://www.gimp.org/downloads/ It is worth noting that I do not endorse the use of copyrighted material unless one has written permission to do so.

You are using two different sprites for the same character. While this can be done, it would be unusual to do it that way. If you wanted to do that, you would always have to hide one of the sprites. This creates an unnecessary complication in your coding. It would be better to rework the images so that you can use them in the game properly.

There are a couple of ways you can handle getting the images:
1. You can copy/paste the images you want from it (for running and jumping) into one separate bitmap, equally spacing the images so that they line up correctly. This would be necessary if you are going to use CREATE ANIMATED SPRITE.
2. You can code it so that the images are pulled off of the bitmap manually and you can then manually animate the sprite.

I have done it both ways and I prefer method 2 myself. Using an animated sprite has it's difficulties, as there is no SPRITE PLAYING() command in DBP. Therefore, you have to look at the frame to see which animation is playing when accepting input from the user. You could do something like

+ Code Snippet

Frame = sprite frame(1)

at the top of your Do - LOOP and then check the frame when the user presses another key.

PLAY SPRITE has to be called every DO-LOOP iteration in order to work correctly. You could do this by changing the starting and ending frames within your code based upon the key pressed.

I hope this is helpful. Please post if you need further assistance.

You need to control the sprite's movement using variables. Working code is worth a 1000 words:

I have attached the .png file that I made from your .gif image that is used in the code. It should be pretty straightforward, so I did not add comments to it.

You can move left or right, even while jumping. I realize the frames are not exactly lined up, but it is only to give you a working example to answer your question.
