Hi, this is my class.
when chociegroup change index, i want my threading image to change.
how should i go about doing it?
thanks for the help =D

[mahesh_aquarius]

try implementing itemStateListner and override the required method and in that method if(item==choicegroup)then change image you need not use canvas and make the code complicated with the above method code will be quite simple.
hope this gives what u want

Hi i need help, according to my codes below, when i run this midlet, my character threading image will change according to the AnimChoice choicegroup upon selection, but this will only work twice, which means i change from walk to jumping, then jumping to walk, and third time changing it, the threading image wont change accordingly, anyone have any ideas?

and one more thing, the threaded image wil be running at a very quick speed, i change sleep(300) to sleep(1000) , the speed of the thread does not seems to slow down. why?

thanks for the help in advance =)
