C2 has the same animation properties as CC.
hen selecting an animation, the Properties Bar displays settings for the animation. These are the following:
"Speed" The number of animation frames shown per second. For example, if set to 5, each animation frame lasts for 1/5th of a second. Set to 0 if you do not want the animation to play (e.g. if a tile set is used with a different tile in each frame).
"Loop" Restart the animation after it finishes.
"Repeat count" If not looping, the number of times to repeat the animation.
"Repeat to" The zero based index of the animation frame to repeat back to if looping or repeating.
"Ping-pong" Play the animation alternately forwards and backwards.

Say you have a ten frame animation of jumping.
Frames 0-4 are the warm-up part that we want to be played once.
Frames 5-9 are the part that we want to loop.
Then set "Loop" to yes and "Repeat to" to 5.
Is that the effect you are looking for?
