Thx you two :)

Could you perhaps explain a bit? So that it gets stuck in my head

@vtrix        grid = 0?1 :0

@newt          Sprite.var%2=0 ?100 :50

I mean.. I get it.. but I did not know the syntax

Guide to Construct 2's event features

See the section on 'Else', and why it fixes events like you've set up.

% or modulo returns the remainder from division so variable%2 would be the remainder of the variable divided by 2. Then as you know, any even number divided by 2 has a remainder of 0, since they are all divisible by 2. That also means any odd number will not be 0.

? : are conditionals. If you do a comparison, like 1=1, the system will take the question mark to mean that anything after ? is to be taken when the condition is true. Then anything after : is to be used if it was false. so 12%2=0 would give you 0 as a remainder, and be true.

Hello got a trouble about 2 states sprite button (switch).
If I move button_1 to bot layer to make the button_2 at top the mouseclick is still affected at the button_1
if I make button_1 invisible and make button_2 visible the mouseclick does'nt work too in all ways the button_2 is not affected by any click because the button_1 is logicaly always present.
Tried destroy or move outside the layout but fail.
