Alright..
Changing the GFX:
3)PlayerAsistant -> public int skillcapeGfx(int cape) { -> Search for the Skill cape ID here
www.itemdb.biz then find it in "public int skillcapeGfx(int cape) {" after that change the number that right next to it, For example,
We going to change the Gfx for The attack cape, The id is: 9747, Which it's: {9747, 823}, {9748, 823}, So you have to change the 823 to whatever gfx you want.
Changing the emote/anim:
Which it's below the Gfx if you scroll down a bit
3)PlayerAsistant -> public int skillcapeEmote(int cape) {
You have to do the same thing, Example for the attack cape: {9747, 4959}, {9748, 4959}, So you have to change the number "4959" to whatever emote number you want.
