Try this setup;
Event Graph
Timeline
In this graph, your pawn will turn and at the same time will move toward that direction. If you want your pawn to first turn and then move, all you need is to add a retriggerable delay node before ‘AddLocalOffset’ node. The delay time should be calculated using the alpha (timeline output value) multiply by the timeline total length. Then you should compare the result with the direction and choose whether to subtract it from the total time length or just use it directly.
I hope this help.
