I have the stickman sprite going fairly nicely.
Bad thing is, when it jumps, the jumping animation is in a loop, so when it goes into that state, it doesnt necessarily start at the start of the animation, sometimes halfway through or at the end. D= How can I fix this?

Maybe you can add rules to set the frame based on the vertical velocity (dy). If dy < -1 then set frame to 0, else if dy < 1 then set frame to 1 else set frame to 2 (if you have 3 frames for example). This would use frame 0 for the part of the jump where the sprite's vertical velocity is upward at more than 1 pixel per frame, 1 when the sprite's vertical velocity is 1 pixel per frame or less in either direction, and 2 when it's falling back down at more than 1 pixel per frame. You'd want to make sure it only does this while in a jumping state, though. Think that'd work?
Or just make sure frame is 0 when you start the jump and see how much that improves things.

hmm, that sounds like it should work. I'll try it in the morning as I'm like too tired to do anything atm... lol
-
Alright that's now working. =D
Now I just gotta do the ladder climbing D=
EDIT:// The solidity isn't working correctly either, i haven't added hills yet, but on the normal flat tiles, the sprite sinks in a little bit for some reason. D=

The images for your sprite are 45 pixels high, but the heights of your sprite states are defined as 32 pixels. That's a relatively easy thing to fix in the sprite definition state editor. That's a pretty cool sprite you got going there. It demonstrates something new to SGDK2 (something that was difficult and uncommon in 1.x) -- sprites with jumping animations... and a pretty nice one at that. Keep up the good work. I may just have to use that sprite myself when it's ready.

ahh, i see. lol

Although you may want to clean up the code a bit. Give things meaningful names, for example, use else-ifs instead of a series of ifs, and at least one place you use if IsInState several times in a row to determine if a sprite is Not in a state, which would be more simply done by using the Not checkbox.

I'm not really sure of what the else-ifs, elses and whiles, do, thats why i never use them. lol

oh yeah... I'm fixing that up now. ;)

Have you looked at the documentation to try to understand them?
-
nope, since everything was working fine without them, i didn't bother. I shall look at the documentation a bit, when i start working on the sprite again.
