How do I pick # or # (not a random range)

I'm trying to set up a random left or right movement once a counter I have set up reaches 0. The thing I need to do is either pick -100 or 100 so that the player will be moved left or right, randomly.

I tried random(-100,100) but it will constantly move left or right because it is picking numbers constantly.

choose(-100,100)

Burvey thanks! though I still seem to be getting a repeat loop, whereas it is choosing -100 and 100 so the player moves left and right until it wiggles its way out of the zone. I tried adding "trigger once while true", but that just caused the movement not to happen at all.

Rather than setting the platform vector x, try just setting player position x.

That did the trick oosyrag, thanks. I had to find the x,y at the bottom of the editor for the 2 x points to pick, but it did the job. I also tried some thing else which also worked:

Just thought, how would I keep the events I have, but apply them to copies of the object that triggers the events? I copied the object but when the player interacts with it like the oringal, nothing happens, though it has the same name, but of course a different ID. Is there a way to copy my object so it does the same as the orginal?
