Fusion Help in Clickteam

how to send number from clickteam to lua function?

I'm trying to do a basic mouse scroll, where the x position of the active is to the opposite of the mouse's x coordinate, but the active keeps showing up off screen to the far left.

Edit: I figured it out

So, I need someone who will help me in creating my game "UNDERTALE: Your Control". If you can - friend request me in gamejolt, and write in comments about you can help me creating it. (Using clickteam fusion 2.5 for creating games)

How do i make an angled coolision like in this game?
Like without any physics engine.

It's like the player is in a box and when the box spins the player can't go outside the box

Why i can't choose the reverse option?

I can't open clickteam what should I do?

how do i fix the screen to look like the other one
