Hi guys,

I have a problem when I try to create multiple sprites with specific images and size ( tried the search option on the forum but didn't quite find the answers I was seeking for . also searched in the Manual but the same issue appeared )

This is one of my generation codes

+ Code Snippet

for turnuri=1 to 100
	
	createsprite(turnuri,1)
    inaltime_cladire = random(15,50)
    setspritesize(turnuri,5,inaltime_cladire)
    SetSpriteColor(turnuri,random(150,255),random(150,255),random(150,255),255)
    SetSpritePosition(turnuri,random(inceput_creeare_claridi,distanta_joc_totala-final_creeare_claridi),90-inaltime_cladire)
    setspritephysicson(turnuri,1)
      
next turnuri

( turnuri = towers in another language )

And this code

canistre = 0
numar_canistre = 20

+ Code Snippet

while canistre < numar_canistre
		canistra = createsprite(200)
		SetSpriteSize(canistra,3,3)
		//SetSpriteImage(canistra, 200 )
		
		unde_sa_fie = distanta_joc_totala / numar_canistre 
		canistra_pusa = unde_sa_fie * canistre
		
		if canistra_pusa = 0
			canistra_pusa = 30
		endif
		
		SetSpritePosition(canistra,canistra_pusa, 20 )
		SetSpritePhysicsOn(canistra,2)
		if GetPhysicsCollision ( canistra , turnuri) = 1
			SetSpritePhysicsOff(canistra)
			endif
		
		inc canistre
		
	endwhile

canistra = gas cans in another language

The questions are :
1) How do I know what ID's are using the towers and the gas cans in order to be touched by the sprite that the player will use?
2) How I can know create the gas cans on the top of the towers , usually the are randomly created and some of them are created inside the tower sprites?

I want to use the most simplest command :

+ Code Snippet

if GetSpriteCollision ( player, canistra) = 1
			DeleteSprite(canistra)
			 
			endif

But this one affects ONLY the last gas can...I'm guessing that the last one has the last ID so the player can touch it. But why not the rest? They are not "technically "created with the same ..ID? while canistre < numar_canistre canistra = createsprite(200)

If is needed i will provided the code translated in English.

Thank you for your time and future answers.

What kind of problem? Your creation code looks ok to me.

Quote: "How do I know what ID's are using the towers "

Well, you specified the IDs yourself:
for turnuri=1 to 100
createsprite(turnuri,1)

Personally, I tend to let the command generate the ID for me and I store it into an array.

From looking at your code, I see a canister is deleted when the player hits it. So I'm guessing it's an item the player can pick up. We can make this more robust using a UDT to set properties to each item. In this case, I'll assume the canister is a gas can and holds a random amount of fuel (for example). Create your canisters in an array just like how I have also done with the towers.

+ Code Snippet


Type Tower
	id as integer
EndType


total_towers = 100

dim towers[total_towers] as Tower


for i = 1 to total_towers
	towers[i].id = createSprite(img_tower)
	setSpriteSize(towers[i].id, random(15,50))
	// more properties set
next i





Type Item
	id as integer
	gas as integer
EndType

total_items = 20


dim items[total_items] as Item

for i = 1 to total_items
	items[i].id = createSprite(200)
	setSpriteSize(items[i].id, 3, 3)
	// more properties set
next i

To check collision amongst all items, you have to loop through all the IDs. You weren't updating the value of 'canistra' once you were done creating the canisters, so it was going to stay the last value it was assigned, which was the last canister.

+ Code Snippet

for i = 1 to total_items

	if GetSpriteCollision(player, items[i].id) = 1
		deleteSprite(items[i].id)
		// or hide it so you're not recreating them in the future
	endif

next i

Marvelous work! It's perfect for what I needed. Works flawless.

About the

Quote: "Quote: "How do I know what ID's are using the towers ""

I was hopping that somehow by using any other method than arrays , I could see each tower ID by using the for turnuri=1 to 100 to be auto-creating somehow ...a wanna-be-array...something like that...( I don't know what exactly i had in mind ...)

I will try using the array to create the perfect position for the gas can creations. ( on the top of the towers ) , and i will come back to say if i managed to succeed or fail

Thank you for your time

One thing you can do for canister placement is randomize the X value only. Then from that point start at the top of the screen and measure down to the top of whatever tower is there. Then you can place the canister right on top of the tower.

can't seem to figure it out.

Tried to use this :

+ Code Snippet

gas_creation_y = 0 ( on the floor )
tower_high_y =  random(15,50)

for canistra = 1 to numar_canistre
		if GetSpriteCollision(items[canistra].id, turnuri[nr].id) = 1
			SetSpritePosition(items[canistra].id,canistra_pusa, tower_high + random(50,80) )
		endif

next canistra

*EDIT*
I forgot to add this :
the tower creation is based on the entire level distance so in order to be created I use this

SetSpritePosition(towers[nr].id,random(starting_distance,total_distance_of_the_game-last_bulding_position ),90-tower_height)

But it seems that somehow it's giving me a crash at the running , but the compiler works perfectly...

What's your idea to place some of them on the top of towers and some of them ( witch have a collision with the tower ) to put them on top ( i've bypassed this a little by using the gravity , and let them fall from the "sky" )
