How do I Detect collision with solid objects

Hi

I'm using a solid object as a button to open a door in my game, button is solid and when the player collide with the button a door opens and an effect that I created would happen, however when the player collides with the button, the game detects multiple collisions with the button and creates multiple effects, but I only need one effect to be created when the player collides with the button. I made the button solid so the player can't go through it. Is there a solution to this issue?

If only the effect is a problem you can add another condition to the event trigger once when true and it will only spawn once.

But this can get complicated for example if you have 3 buttons and 3 doors in a level, you will need to keep instance variable for each button with different value so you will know what button is pressed.

collision is a trigger itself, trigger once doesn't work with it

Oh yeah I forgot about that, well you can limit it with a variable then. Add global variable lets say its called temp set it to 0 on start, and add extra condition on the event temp == 0, then as soon as the trigger fires in the first action set temp to 1, so its only triggered once.

Yeah I had this in my but it was conflicting with something else in the game, however I fixed the issue, thanks
