How to make the movement only diagonal in 4 directions? The direction of movement is 45 degrees

Bullet, set angle - off

Solid - on

On collision it turns out that the angle changes not 45 degrees

It needs to be like in the picture below

You can round the angle to 45 degrees after the collision.

Set angle to round(((angle+360)%360)/45)*45

You can round the angle to 45 degrees after the collision.

Set angle to round(((angle+360)%360)/45)*45

How do I understand what angle value to put in the brackets? Or do I need to use some global variable?

I haven't been able to do this for two days, I've done everything else. If it is not difficult you can make me a project and send it to me

Change angle to sprite.angle or whatever name you gave the object.

Or since you are using the bullet behavior with “set angle” to no, you’d want to use the action:

“Bullet: set angle of motion” and use dop’s formula with

round(((sprite.bullet.angleOfMotion+360)%360)/45)*45

doesn't work

So it doesn't work because it can go vertical or horizontal sometimes? We can modify the formula further to only have angles at 45 degrees. Probably this:

round(((sprite.bullet.angleOfMotion+45+360)%360)/90)*90-45

For a single object you could also basically do the motion manually with two variables for the x and y velocity, then use overlapping at offset to see when to bounce. Logic would roughly be:

start of layout
-- sprite: set vx to 1
-- sprite: set vy to 1

sprite: overlaps wall at offset sprite.vx, 0
-- sprite: set vx to -self.vx

sprite: overlaps wall at offset 0, sprite.vy
-- sprite: set vy to -self.vy

every tick:
-- sprite: set position to self.x+self.vx, self.y+self.vy

I'm happy! Thank you all so much )

For a more deluxe and precise way you could move overlapping objects out of each other and calculate the collision normal at the same time to bounce off of. Construct doesn't have a built in way to do that so here is a way to do it between axis aligned boxes by utilizing an algorithm called the Separating Axis Theorem.

I take it that for multiple sprites this won't work. I can't figure it out

There is a nuance. When there are many objects (in my case 20)

The angle of motion and speed changes

I didn't know you'd need more than two objets. I'll think of another way to do it for many objets.

I'll look forward to it
