Is it a Constrain Self.positionX ?? or Self.MotionX ??

When touched, constrain X to min(max(mouse X,700),900)

No real need to use a Constrain in this situation, a Constrain is basically 60 instructions a second, every second, all the time, whereas a Change attribute is a single instruction.

when player presses the right button "SeedNO." attribute increases by +1

When [snapping to grid] AND attribute self.placed=false

Add a self integer attribute, call it id. We'll use this to work out what image to display.

@tatiang Thanks a lot got it working . My final question is how do you now make it unmovable. It snapped to the grid but I don't want that grid to be able to put anything else in and the object can no

Choose a problem by changing an attribute game.row to random(1,tableRowCount(tableName)) or just increment it to go in order.

I'm trying to reference a table with attributes to display text, but it keeps coming up with an invalid expression. The table is working fine as when I refer to it directly (rather than with an attrib

I think I understand how to use attributes to generate the random numbers I need for the math problem.

What does "Better Collisions" do? I know you can have custom collisions, but not sure what better does

constrain motion linear velocity

I watched a tutorial on making a platformer game Danger Droid, I think it was from @jamie_c. In the tutorial, Jamie used constrain attribute motion linear X instead of move command to move the player.

You can create a boolean game attribute , call it mute

You want two real attributes (Touch_Start) and (Touch_Stop). Then make an actor on the background (size of whole screen) and when touch--> is down :: change attribute Touch_Start) to mouse.post
