Spell Casting with Projectiles

Arcade Help
1

I am making a dungeon crawler game and i can’t figure out how to get spells to cast properly. I started off by using just projectiles then tried darts but it would not work, spells wont cast in the direction i am facing. i am on a laptop that is not the best so solutions using not much code would be appreciated. Thankssss

If you want it to shoot at an angle, do this:

vx = cos(angle) × speed

vy = sin(angle) × speed

Beware, it uses radians, not degrees. Could you send a link to your project?

Sure! i will paste the share link (btw the game sucks right now) https://arcade.makecode.com/S58310-10223-28059-10450

also, could you translate that to blocks?

If you only need to shoot when walking, this should work:

This code isnt the best but its simple and works, but if you wanted to shoot while standing still, it would be a little more complicated with variables, but surely doable. Would you want that or is this enought for your game?

Here you go!
I added the “timers” extensions, which has a few VERY USEFUL blocks that help with cooldowns, timing, and that kind of stuff. Anyways, I added one handler around the damaging code and made it so you can only lose health once every 500 milliseconds.

For the vanishing, you could create another “on overlap” block, and fill out the parameters by making the first sprite your projectile, and the sprite kind the kind of your enemy. Then inside the event add a destroy sprite block and replace the “mySprite” in there with the “othersprite” parameter from the “on overlap” block.
