How do we know the distance with the distance block

moutamou

Hello im making a strategic game, and i want to make that if an ennemy is near ===> shoot him, so i want to use the

(distance to [ v])

block which can be really useful, but i don't know how we can actually know how much it is, can someone help me?

Nezon

([sqrt v] of ((((x :: grey) - (x position)) * ((x :: grey) - (x position))) + (((y :: grey) - (y position)) * ((y :: grey) - (y position))))

Can you explain? Thank you

The distance means the amount of pixels away from an object.

yes i know but i don't want to count all the pixels to make a range

I didn't understand your last post, but going off your first one, to know if an enemy is inside a range of the weapon, suposing there's only one thing that shoots, you can put a script like this inside the enemy sprite:

if (distance to (NAME OF THE THING THAT SHOOTS)<(DESIRED RANGE IN PIXELS)) than:
DO SOMETHING

or, depending on the case, put inside the weapon:

if (distance to (NAME OF THE ENEMY)<(DESIRED RANGE IN PIXELS)) than:
DO SOMETHING

To decide the DESIRED RANGE IN PIXELS, you can just try different values.

Suposing there are multiple enemies and multiple weapons, than you'll need to use a list to store the positions of the enemies and calculate the distance to the weapons using:

Sqrt(((ENEMY.X-WEAPON.X)*(ENEMY.X-WEAPON.X))+((ENEMY.Y-WEAPON.Y)*(ENEMY.Y-WEAPON.Y)))

instead of the distance to block.

If you didn't get how to detect this, could you share the project link so that I can take a look at it and explain for the specific case?

Oh, sorry, I didn't get the question the first time I saw it, I tried making a project to visualize the area the distance covers < https://scratch.mit.edu/projects/615110891/ > just enter a certain distance and it'll show you the range it covers. It may lag a little bit, but it's because it's using run without screen refresh.

If the object you want to shoot is less than a certain distance away, you should make the turret shoot. That creates a radius of covered space.

so you don't want it to be exact? i dont get why you would want that

when green flag clicked

forever
if <(distance to [ v]) = [...]> then
turn cw (15) degrees

endend
