Help with shooter game

1

Can anyone help me with the sprite guard shooting at the player??? It would help me a lot. I’ve always wanted to play a shooter game. I know everything I should happen at that and at that point. I am writing this with a translator. I come from Germany. If someone doesn’t understand me, it’s not bad because I can describe things very badly. Just write to me!


if Training001 then
    background()
        sprite(Wache, 850, 500)
        sprite(Spieler, x, y) 
        sprite(asset.builtin.Blocks.Cactus_Inside, 200, 250, 250, 400)
    sprite(asset.builtin.UI.Blue_Button_07, 200, 420)
    sprite(asset.builtin.UI.Blue_Button_07, 300, 250)
    sprite(asset.builtin.UI.Blue_Button_07, 100, 250)
    sprite(asset.builtin.UI.Blue_Button_07, 200, 100)
       
    end

I think you will need to tell us a bit more than that.

What sort of shooter game? Can you share some pictures of the type of game you want to make?

@Killer.Jo - just looking at your code we can’t see how it fits into the rest of your code without seeing it. Does this relate to the code you posted in another thread?

4

@Bri_G @sim I just need a small code where the sprite (“WACHE”) shoots at the sprite called “SPIELER” with small distances. It is simply to be “thrown” a sprite in the direction of “SPIELER”. Is that enough?

5

@Killer.Jo - I’ll just post this little piece of code to try to show how it should work. It’s untested as I don’t know what the rest of your code does. So here’s how I think it would work.

You take the position of SPIELER and the position of WACHE then calculate the x an y distance between the two. Assuming the x an y distances are different, you increment on the smallest distance as an integer (effectively) and for each of the other x/y distances you multiply out in the loop and floor the answer to try to keep the line of travel as straight as possible.

Then place your sprite based on that calling the drawing routine from your draw() function.

Hope that makes sense.

Now here is roughly how I expect the code to work.
Call the routine to calculate the distance first.

Note - you may need to adjust the signs of the distance depending on where WACHE and SPIELER are relative to each other.

Edit: realised later that loops for sprite movement shouldn’t be used here, modified the code to increment on screen refresh by using count as a variable incrementing each screen cycle.


function findDistance(v1, v2)
    -- v1 is WACHE, v2 is SPIELER, Calc distance
    dist = math.sqrt(math.abs(v1.x-v2.x)^2+math.abs(v1.y-v2.y)^2)
    count = 1
    return dist
end
    
function shoot(dist)
    -- 
    
    if (v1.x - v2.x) > (v1.y - v2.y) then
        -- loop on height
        incY = 1
        incX = (v1.x - v2.x)/(v1.y - v2.y)
        sprite(bullit, math.floor(v1.x+count*incX), v1.y+count*incY)
    else
        -- loop on width
        incX = 1
        incY = (v1.x - v2.x)/(v1.y - v2.y
        sprite(bullit, (v1.x+count*incX), math.floor(v1.y+count*incY))
    end
    If count > dist then count = 0 end
end

ATTENTION :warning:: This code has partly included CurrentToch because there is no other way.

This is the whole code. I don’t know why it doesn’t work so I want the Sprite GUARD to shoot a small “button” (on the sprite PLAYER) so that a small button is “thrown” to the sprite “PLAYER”. It’s not meant to be mean now : ) I just wanted to explain to them briefly ; )

Hello??

I must this write

Sorry in slow response KJ but - I’m a little busy at the moment, part the way working through your project but having to re-write a lot of it as Currenttouch in particular makes very messy code to read and interpret.

You would do better to use the touched(touch) function and keep most of the touching interactions there. Using Currenttouch is handy occasionally to capture the odd event.

Note if you use function touched(touch) all aspects of the touch are saved in the touch variable array so you can check many conditions by interrogating the array.

Codea runs setup() once then loops through the draw() function and the touched() function with each pass, which makes it better to use the touched(touch) function for that reason.

Hopefully I’ll finish the coding for you today and post it later.

It’s not bad. But I had to use currenttouch because if you used toched, it didn’t work properly
