Character Animation Component
by Jester Carvalho · in Torque X 2D · 09/19/2010 (4:48 pm) · 2 replies
I am trying to create an animation and simplify its fire component when asked to find last rotation. Right now i am using a modified version of Darth's AnimatedCharaterComponent from his "Arena Shooter" tutorial. What I am trying to accomplish is having 1 walking animation and 8 direction (rotation) animations. This may be more simple then i am trying to make it. I want to be able to Use left thumbstick (or w.a.s.d.) to move forward, back, and side-to-side, and right thumbstick (or up,down,left,right) to control the rotation and call on that directions animation. This way when our "Player" is facing 1 direction we can still strafe or move forward back still fire in the same direction. As it is now after the modifications (aka messed something up), my player rotates and i can get him to strafe but i have to use both w.a.s.d. and arrow keys at the same time. Also my "Player" fires north unless a arrow key is held down and the fire button is pushed. I think this error is from my character component but not positive.
Here is my cs file.

This worked Great. Thank You. Solved My first Problem. Now trying to Solve my next Problem. My character now does not play any animations when using left thumb stick. (this is my doing) I took out the play specific animations to keep from looking in 1 direction and shooting in another direction. I am now trying to figure out a way to call on "LastAnimation". I know this must be possible just don't have the experience to figure it out. I am attempting to do this so it looks as if the player is walking not sliding when a direction is pushed. At this point not trying to implement a strafe animation or walk back animation just same animation that my "Player" was playing when I rotated him last. I will update the code above so you all can see the changes i have made. Again Thank You Alex for your quick response. Line 138 is where I try to call on "PlayAnimation" and does not do a Darn thing.
