X Axis flip with Xbox Controller
« on: April 20, 2017, 06:38:40 PM »
Hey guys, I am new to unity, this is probably my 5th week with it. Playmaker is making things a ton easier, as I am a art guy.

I am trying to flip my sprite with comparing the x axis. I get the float thing, but the thing I do not understand is how to store and use the vector 3. I cannot for the life of me get the vector to flip depends on the +/- of the x axis.

Please help!!!

I am not sure I get the situation 100%, so if my advice doesnt help, please let us know more about it. Sometimes it best to just describe what is happening in the game in plain language.

So you can make vector 3 variables just the same as floats. Vector 3 contains three floats together in one neat little box. It has a float for the x, y and z axis of your game object (a sprite in this case?). If it is a 2d game, it only needs a vector 2.

In the actions section of playmaker, there is a whole catagory for vector3 and vector 2 actions.

If you want to just compare the X from a vector 3 (which always contains all x y z, in that order), you can get the X "out" from the vector 3. Use the action "Get Vector3 XYZ". This will allow you to store the X into a float variable.

Once the X is in a float, you can do a float compare more easily.

(There is even an action to do the opposite. You can "make" a vector3 from three seperate floats. One float for each x, y and z. If you fail to set a float for one of those three axis, it will be 0). The action is called "Set Vector3 XYZ".

Summary: Really there is nothing too magical about vector3. Basically they were invented for convenience, so we don't need to always set 3 different floats each time. We use them pretty much exclusively for the position of things in 3d space. They can be set/get like any other variable type (string of text, float of numbers, etc). But sometimes we do need to get the floats out of vector3s to do specific things.

Hi,

 You can simply store x in a fsm float, then multiply it by -1 and set it back into the vector. have you tried that.

 Also, for fliping sprites you could simply use the scaling ( -1 will flip), and

Also, Have you studied the 2d platformer sample I recreated 100% in PlayMaker? I flip sprites too for the character.

 And, I Also just created two new actions on the Ecosystem to set and get the flip values on a sprite, so that it's gives you more options to flip your sprite.

Bye,

 Jean
