So my latest experiment is making a game similar to the ones years ago, where a character would "slide" from obstacle to obstacle.
So when the player hits a movement key, the character slides in that direction. You can't stop the sliding until the character is stopped by a collision with the wall or a blocked creature.
The combat mechanic is when you hit a creature you push it (and cause damage) unless there is something behind it (it becomes blocked), in which case you just cause damage.
I'm trying to figure out where and how to do this. I saw a collision projection or something somewhere, and trying to work out how to leverage the move controller and/or keyboard controller to a) determine the state to see if he's moving or stationary, and b) how to make him move in the direction pressed.
This works, it's like he's got a jet strapped to him permanently, flying left or right. Collisions with the spritesets with collisions (tiled -> utiliti) do stop him moving, but the Tiled tiles with collisions do not (I don't think they are being imported).
````// If moving, keep moving unless blocked
if (this.getState() == PlayerState.CONTROLLABLE)
Game.physics().move(Knight.instance(), Knight.instance().getAngle(), 10);}````
Screenshot to visualise. No, that's not a skeleton, it's a Knight in very shiny armour and a skull helmet... #programmerart

Hi,
Welcome to the community. Currently, the tileset collision that you define in the Tiled editor doesn't automatically generate ~~~~CollisionBoxes in the utiLITI editor. I checked the code behind and we don't implement deserializing this information at all.
The LITIENGINE doesn't support tileset collision right now. However, I think this is a very useful feature and I've created the GitHub Feature Issue: #335 to tackle it. Thanks for your input!
To work around this, you can just generate collision boxes in the utiLITI editor around the areas that you want to block off. That's the current way of doing things but I definitely think we should support the tileset based collision.
(At least to some degree, because tiled allows for polygons to be defined and the LITIENGINE's physics are based on rectangles).

steffen nice! I'll use the collision box in the mean time, I was going to create entities as wall objects with collisions as a short cut.
Any tips on changing the movement?

After some research into your ludum dare code, I found what I needed for controlling movement (specifically the Dash from Lupus) and went on from there. I used ability and effect, but I'm learning your framework as I do this and that I probably don't need to use those classes. I also found a weird effect where moving at angle 0 would stutter in random directions, probably artefacts from a high or low value or duration.
