Star Beam Blast Goes Through Collision. Need Help!

[LebronJamez69]

I am making a star beam blast that pushes allies and enemies with a knockback effect. However, when I use the ability near the water, the star beam blast would push them from the land into the water due to no collision. Is there a way to fix this in Jass? Thanks!

An item with 16 colision size is often placed on co-ordinates to check pathability in which case two things can happen.
1. The item gets placed exactly on the co-ordinates
2. The item cant be placed on the exact co-ordinates so its placed nearby
Then a check is made to see if the item is located at the co-ordinates it was originally created at. This check is fairly good but a problem occurs when a 16 colision size item is used to determine if a 32 colision sized unit can fit somewhere. There are knockback systems such as GUI Knockback 2.5D v4.2.5.0 out there that handle it better.

    call SetItemPosition(udg_K2DItem, udg_PrkX, udg_PrkX)
     if GetWidgetX(udg_K2DItem) == udg_PrkX and GetWidgetY(udg_K2DItem) == udg_PrkX then
    call SetUnitX(udg_PrkTrgt[udg_PrkInt], udg_PrkX)
    call SetUnitY(udg_PrkTrgt[udg_PrkInt], udg_PrkY)
    endif
    call SetItemPosition(udg_K2DItem, udg_K2DMaxX, udg_K2DMaxY)
    call SetItemVisible(udg_K2DItem, false)
