I've almost completed the coding of my platform game and I want to add a new feature, an item that flips controls for some 20 seconds.
I could go back to the code (which is very complex) and add the feature, changing a lot of lines. But I wonder if there's an extension or another method of flipping the input controls directly, so that when the player presses left (on the keyboard or joystick) the runtime takes it as if it was right, etc.
The easiest way I can think of is to inject a multiplier into your movements. I don't know if you are using any custom plugins, but it should still work. Any time you are taking an input that changes x/y, multiply the result by a global value. The global value would be 1 under normal play, and set to -1 under reversed conditions. This due to the fact that multiplying by 1 yields the same number, and multiplying by -1 yields the negative version of the number.
On Press Left: set X(Player) = X(Player)+(2*reverseMod)
Thank you.
But that requires to modify many events. Is there an extension which can simulate an input (key or joystick)?
The Control X extension can simulate key presses... but I think it would still have to sit in the middle of your events and you'd code around it, as it wouldn't stop the reaction to the original keypress (if simulating pressing Right when pressing Left, you would end up with both keys down).
If you're using the default Player object for controls, is there a way to switch the keys for left and right temporarily from there?
That's exactly what I'd like to discover. For the time being I've managed to find a workaround: I flip the entire screen with a flip shader so that the controls seem to be reversed!
You can do this with Control X. Just set the controls to opposite buttons when they should be flipped and set them back when they're normal again. This only requires 2 events and is much faster than changing every event that uses controls.Originally Posted by DavidN
Sure, but if the player had defined custom controls? If he manually set I / J / K / L for movement can I retrieve that J is for left and L for right in runtime and swap them temporarily, before reverting them to normal?
And if the player chose to use the joystick?
I've made an example for you. If you touch the red object, you will get your controls flipped for a short time.
Thank you for the example! It works very well with keyboard controls. But it does not affect the use of a joystick/gamepad.
