I have a test level for testing things in my concept ROM Hack, but there's a problem; I placed a ? Switch in the test level which will trigger an event ID (Placing wood blocks to be a bit more specific), but the ?-Switch disappear whenever I will start the level.

I've tested a few times on an event that destroys tiles on both of my test level and my concept 1-1, but I can't see the zone, it must work perfectly, but I don't know the problem yet.

In the concept 1-1, I modified the level to be able to press the ?-Switch in the area I've pressed the ?-Switch, but the blocks doesn't destroy, I just don't know why.

The Raw Sprite Data for the curious one (From the test level)

The ?-Switch's RSD: 02 00 00 10 00 00
The Tile creator/destroyer (Tile god)'s RSD: 00 02 00 00 41 04

Is the switch red in editor? If it is you have to enable it in sprite sets

No, the 3 switches are usable everywhere, I've watched a NSMBe tutorial about sprites earlier today.

Oh. I didn't know that maybe because I don't use switches very often but anyways I don't have idea of what happened to you sorry

Have you set the target id to insert number of the event here
And not trigger id, bacause if you set trigger id to for example 1, the switch won’t Appear if you don’t trigger the event number 1
(I’m not at home, so i can’t see your raw sprite data)
