[QUOTE=eony321v] [QUOTE=Shindoh] I don't really know the Physics Behaviour that well, but from what You are saying, it sounds like moving up a slope is no problem for You? Just adjusting the angle of the Player Sprite itself (the rotation)?
You can easily do this by comparing the LastX and LastY (private variables, that You assign the .X and .Y position to, at the end of the Event Sheet) position with the current .X and .Y position, by entering the values into the angle expression (a system expression).
It will then give You the angle the Player is moving in; You then just set the Player Sprite Angle to this.[/QUOTE]
Can you please explain this more detailed or make a cap?
Okay, the basic idea behind finding an angle is having two points at different positions.
Imagine a coordinate system, a graph. Now You enter a point at (5, 5) -> (X, Y). The point is at 5X and 5Y in the coordinate system. Now let's make a second point at (10, 10). It should already be obvious when looking at this graph, but then You connect the two points.
Now relative to the X and Y axis, that means, when You compare the line You just drew to the X-Axis and the Y-Axis, it will be 45 degrees.
You could get the same result, by entering a point at (0, 0), and (1, 1), this would also equal a 45 degree angle.
So what we need first is two points to compare, the last position, and the current position of Your object. In the current tick (the current frame of the game), how do we get the last position?
First we give our object two private variables, a LastX and a LastY variable. Then we need to assign them. Now we want to have the old value, before any new movement is added in the Event List.
If You were having Events further down Your Event List, that move the Object, we could just assign the current .X and .Y position to LastX and LastY at the top of the Event List.
See it this way, the Event List is checked from top to bottom.
Now, it will first fill the LastX and LastY variable with the current .X and .Y (let's say 5X and 5Y), further down You have an Event moving the object to the right (X+5) and up (Y-5). So now the current .X and .Y position in this frame, this tick the Event is checked, is 10X and 10Y, while LastX and LastY are still 5X and 5Y.
So below the Event for movement, we can now compare the two. Because LastX and LastY will only be assigned again in the next frame/tick of the game (at the top of the Event List). But in the current tick, it hasn't been changed yet.
