I have set all of the bullets as collision type 3
some of the enemy ships are type 2
some are type 1

when I do a for-next loop to cycle through the bullets how do I use entitycollided to find out which enemy ship was hit?

Or when I cycle through the enemy ships how do I find out which ship was hit?

I tried using

For tr= 1 To 100
hit_ship= EntityCollided (bullets(tr),1)
If hit_ship<>0
HideEntity hit_ship
EndIf

next

but hit_ship is always zero no matter how many times I see the bullet collide

The only way I can identify which enemy ship has been hit is by giving each INDIVIDUAL enemy a collision type which slows the game down to 1 FPS

CAN ANYONE HELP?

Your code will only check bullet 100, as hit_ship is owerwritten before you check if it's <>0. Move the next command down below endif.

I tried that and it still doesnt work, check my code again

Eh, you did remember making a collisions statement?

for i=1 to countcollisions(bullet)
hideentity collisionentity(bullet,i)
next

k=0
For p.blue_ship=Each blue_ship
k=k+1
For t = 1 To CountCollisions(redbullets(k))
HideEntity CollisionEntity (redbullets(k),t)

Next
next

I tried this but it doesnt work.

Definetly set the collisions because the bullets stop when they hit the enemies

Thats not going to work though is it?

how many bullets do you have? If there is only one ship then you are only checking 1 bullet, even when there are 100 of them.

Read your code again.

You set k to 0. No problem. You then loop through all the ships (not bullets) increasing k each time - you then check the amount of collisions that bullet k has. The problem is you're only going to loop through as many bullets as you have ships. If you have 3 ships and 100 bullets you will only check the firt 3 bullets. Have 100 ships and 3 bullets and theres a good chance you will get an error of some sort.

you need

for b=1 to MaxBullets
   for i=1 to countcollisions(bullet(b)) 
      hideentity collisionentity(bullet(b),i) 
   next 
next

Forget about looping through the ships. That doesn't matter.
